The economy vs covid suppression: a false dichotomy

A number of commentators are suggesting that policy makers face a major trade off between prosperity and disease prevention in response to the coronavirus. Those who are doing so are largely, though not exclusively, arguing in favour of more relaxed social distancing measures to prevent job losses and loss of income to businesses. Readers will come to their own judgements about the morality of such arguments if this tradeoff exists. I'd like however to make some arguments for why in my mind, this tradeoff is likely to a false one.

1. If very large numbers of people become ill, they drop out of the labour market while they (hopefully) recover. We can't say for sure precisely what proportion of Covid cases are truly asymptotic, but a reasonable guess based on countries like Iceland and Korea with very large testing programs is not more than half. This means that if Covid spreads uncontrolled, large numbers of people drop out of the workforce regardless. It also means that those involved in key professions (NHS, food distribution, water, gas and electricity supply etc etc) who will have to try and continue to work in any situation are more likely to become ill, as higher rates of infection in the general population mean any given individual, key worker or otherwise, is more likely to become ill.

2. Very high levels of spread of the Covid could well lead to panic. Lockdown or otherwise, people with savings or supplies might simply refuse to go to work, whether their employer allows them to or not. Those who are don't have the economic security to do this might just tell their employer they have Covid symptoms and need to self isolate. 

3. Failure to enact suppression strategies will not be a politically sustainable option. If, as is likely, countries which stick to suppression strategies see a significant short term reduction in new cases and fatalities, any government which took a different route or reversed suppression measures prematurely due to 'economic' concerns would face extreme political pressure to introduce or reintroduce suppression strategies. 

4. The faster and more thoroughly you enact suppression strategies, the more quickly case numbers fall and you can legitimately start to think about easing things off. Getting ahead of the curve sooner means not just lower fatalities in the short term, but a shorter period of economic disruption. 

5. The long term economic damage from coronavirus isn't just about disruption this year. It's about what the labour market looks like after this is all over. Very large numbers of infections means, for reasons too grim and too obvious to spell out, a period of difficult adjustment in the labour market.

The broad thrust of these arguments is pretty simple. One way or other, we are going to see a period of major economic disruption. The choice is whether governments get ahead of the curve, and keep that period as short as possible, or let things get out of control and face the same, if not greater levels of disruption for a longer period of time. 

Social distancing fatigue

Part of the government’s current thinking on coronavirus seems to revolve around the idea that after a certain point, the public could become ‘fatigued’ at control measures, meaning they would become less and less effective. This, so it is argued, might justify postponing the implementation of social distancing measures to a later date. At the risk of becoming yet another non expert who should shut up about this, the underlying logic of this seems dubious, but I’ll try and reconstruct it as best as I can.

It’s true that some social distancing measures have to be delayed, as they can only effectively be implemented once you know where the mass of cases are (e.g restriction of travel to and from particularly affected areas). But some things can be done across the board (e.g school closures, banning large gatherings). So far as I can tell, these slow down infection rates irrespective of absolute numbers, provided there is some spreading to be reduced. Now, if you assumed that you could only implement social distancing measures for a short period of time, once, it might make sense to try and reserve this for the time you thought would be the peak (if nothing else to flatten the curve enough to help hospitals).  But this would be true if and only if measures carried out earlier did not prevent this high peak happening in the first place. The overall trajectory of the infection would have to be largely unaffected by earlier social distancing measures, just delayed.

This overall trajectory, presumably, would be the virus infecting a large enough proportion of the population for herd immunity to start kicking in and slowing down the rate of new infections. In other words, you basically have to assume that sooner or later, a very large part of the population is going to get infected and you can only implement social distancing measures for short time periods.

This seems like a rather bizarre position at a time that China and Korea seem to have managed to dramatically limit new cases to absolute numbers converging on something like 1/20,000 and 1/5000 of their respective populations. This seems to suggest that preventing large portions of the general population getting infected is very possible. Even if you don’t eradicate the infection entirely, extensive contact tracing and testing might well be enough to prevent the outbreak from ballooning again once numbers have been brought down through social distancing. But such measures would presumably only be possible if numbers were small. Even if you ended up with a bit of a cycle of lower and higher levels of social distancing measures, this would not need to be carried out in perpetuity, just until more effective treatment or vaccines were developed and mass produced.  

In effect, the logic behind delaying social distancing, if government statements are taken at face value, seem very shaky indeed. They are applying highly speculative behavioural science (can anyone find a citation that supports social distancing fatigue kicking in at specific time points?) in a way that even if true, require quite specific understandings of the spread of the disease which don’t seem to fit the pattern of what is occurring in countries with more rigorous social distancing measures. And that’s before we think about what ‘fatigue’ would actually result in (people can’t go to sports matches that aren’t happening, even if they want to). No other developed country has explicitly endorsed such a strategy, presumably because the risks are so asymmetric. If the government is right, they perhaps make things slightly easier in a very bad situation. But if they’re wrong, they will be the people who allowed the UK to see extremely widespread infections, when other countries avoided such an outcome.

Is expansionary fiscal policy good or bad news for Labour?

There has been a lot of speculation recently about whether Johnson's government will embark on a major program of public investment funded by borrowing. There have certainly been big promises on additional spending in health and the police, and the decision to press ahead with HS2 is a major spending commitment. Taking the statements of the current government at face value is certainly risky, and this isn't the first time there has been speculation about the end of austerity. In the early day's of May's premiership, there was plenty of talk about the end of 'Osbornomics', and whether Hammond would significantly relax the fiscal framework the Treasury was operating under. This did not amount to much. But let's assume for a moment that Johnson really does go for a major deficit spending splurge. Obviously this would have big implications that go beyond politics. But one, admittedly limited, question that that this raises in my mind is what implications this will have for the Labour Party going into the next general election. Does this make life easier or harder for progressives?

The way I see it, there are two countervailing forces  at work here. On the one hand, in some ways this would seem very bad news for Labour politically. For the last 10 years, austerity, in the face of low interest rates and persistently slow growth have been something of a massive open goal for Labour. It presented an easy way in which an opposition party could promise to make people's lives better without huge tradeoffs. Just spend more money on stuff people want, and let fiscal multipliers take care of the debt to GDP ratio, and use near zero interest rates to invest in infrastructure projects which will almost certainly generate non zero returns. OK, there are limits to how far this can be taken, and in any case may mean only modest increases in current spending with larger increases in capital spending. And there are plenty of other goals a left wing government would want to pursue, like reducing income inequality, that this does little to address. But it still represented one easy way in which Labour could plausible say they would make things better without obvious losers. Indeed, the business friendliness of expansionary fiscal policy was something that Labour did not properly exploit (austerity, combined with Brexit, made the Conservatives anything but the party of business). If these easy wins are taken out of the picture, life may get more difficult for Labour by the next general election. And if the Conservatives take expansionary fiscal policy too far, and focus too much on things which don't generate investment returns, Labour might even need to start worrying about deficit reduction.

But the collective psychology of austerity is a strange beast. As Chris Dillow writes here, austerity seems to have lowered expectations about what a government can do and whether a government can make public services better. In some ways this is a variation of an old phenomenon: underfund a state service so badly that people lose faith in the ability of the state to run that particular service. But with austerity this is more pervasive: the every day reality of stagnation becomes a kind of cynical realism, and promises that involve life getting better are easy to shrug off as unrealistic fantasising. This kind of kind of cynical realism is, of course, advantageous to the party that proposes the least economically active state. Persistent low growth also has a habit of making politics meaner, angrier and more focussed on finding scapegoats, all of which is conducive to the kind of culture politics progressives seem to be on the losing side of at the moment. Expansionary fiscal policy could, then, even undertaken by a Conservative government, be good news for Labour. By showing that the government can do good things it might raise expectations in a way that makes more people a little more receptive to manifesto pledges, and if it raises growth it may dampen the appeal of nativism.

All of this, of course, is rather overshadowed by the Brexit shaped elephant in the room, which may well lead to a major economic shock in the near future. But taken on its own terms, the political effects of expansionary fiscal policy are rather uncertain. It is unclear whether Labour Party strategists should greet recent expansionary noises positively or with trepidation.

Language and the selectorate problem for the left

Paul Krugman is worried about a Sanders candidacy. Not because of what a Sanders presidency might mean in policy terms, but because he bandies around terms like 'socialist' in a way that provides easy lines of attack for his opponent in a presidential campaign, when a term like 'social democrat' may be both more apt and less open to mischaracterisation. What I think is going on here is part of a broader problem for the opposition parties in both the UK and the USA. For both the Labour Party and the Democrats portions of the selectorate are providing incentives which damage the parties' prospects with the wider electorate. This is partly a question of style and partly about different meanings and idiolects that exist within the contemporary left.

Forget for a moment what the true meaning of terms like 'socialism' is and whether they can include what is essentially a program for a more robust welfare state, greater income redistribution and improved workers' bargaining power in the context of a market economy. Yes, it's true that many European social democratic parties have the word 'socialist' in the name, but historical nomenclature can be misleading. Once upon a time the Bolsheviks were the a faction of the Russian Social Democratic Labour Party. The real question here is what associations people actually have with the term. To many on the left in the UK, 'socialism' might mean buying a coffee from a vendor on a living wage, on the way to a better run train service taking you to a job with proper protection as an employee. But like it or lump it, to many older voters it still refers to an economic and political system based on state ownership of the means of production and distribution, and carries with it the legacy of the iron curtain. Words can mean whatever we want them to mean, but effective communication requires a common understanding of this meaning. Maybe associations can change, but that takes time, and time is not on our side.

The problem is using terms with this kind of ideological baggage has big payoffs in leadership races. To portions of the selectorate, it signals a clear break with the worst aspects third way centrism and the perceived timidity of the centre left after the financial crisis. In the UK this is partly a response to Milliband's attempts to triangulate on austerity, and in the USA the inadequacy of the Obama fiscal stimulus and piecemeal nature of healthcare reform, both of the latter largely being a result of political impediments to anything more comprehensive. This kind of signalling is not limited to the use of the term 'socialist': in the Labour leadership elections it has become something of a necessity to describe anything and everything as 'radical' and to fetishise outdated markers of social class as a means of establishing authenticity.

The tragedy of this is it distracts from the fundamentally conservative character of much of the program of the modern left. It is about preserving the welfare state and saving it from starvation through underfunding. It is about defending the tremendous social progress of the last 40 years, of societies that have become more inclusive of minorities, in the case of the UK much more multicultural, imperfect and incomplete as that progress may be. It is about defending the rule of law and upholding liberal democratic norms in the face of their assault from authoritarian populism. And it is about protecting the environment for ourselves and future generations. This kind of conservatism is harder to paint as radical and threatening, but the left finds itself in a kind of trap. The signals you need to send to win over substantial portions of the selectorate may be major hinderances with the wider electorate.

Small 'c' conservatism and the Labour Party

‘To be conservative, then, is to prefer the familiar to the unknown, to prefer the tried to the untried, fact to mystery, the actual to the possible, the limited to the unbounded, the near to the distant, the sufficient to the superabundant, the convenient to the perfect, present laughter to utopian bliss.' Against the backdrop of current political developments, Oakeshott’s description of conservatism may seem a little off the mark. But self descriptions always need to be treated with a little bit of suspicion: no doubt many Communists would have said and believed that what they were doing was in the name of human freedom and about ending subjugation. But as an aspiration, this idea of conservatism doesn’t seem like an altogether bad one, though I think we should be suspicious of liking the familiar or rejecting the possible for the actual for their own sakes. Caution, a desire to preserve and build on the good aspects of what exists, empiricism and a suspicion of utopianism are not all bad things. Conservatism, in this sense, may be better represented by the left of British politics now, and perhaps this is something the Labour Party should embrace. 

Much of the agenda of the contemporary British left is, after all, about preservation. Preservation and restoration of the welfare state, of a flourishing public sphere, of the post war diplomatic order and of a tolerant, pluralistic, multicultural society. What we are essentially describing here is conserving and building on the gains of the 20th century. Environmental protection and combatting climate change is a more striking example still. How, then, would this this with the increasing demands for ‘radical’ change, and for the increased interest in ‘systemically’ criticism, in particular with capitalism and the market economy?
How does this fit with the rehabilitation of ‘socialist’ as a self description? I’m not convinced there is as much substance to these terms anymore as might appear at first glance.Very few people are advocating a planned economy, or for that matter any kind of coherent means of organising economic life that is dramatically different to the status quo. No doubt the contemporary left in the U.K. has a particular interest in nationalisation, but this tends to be limited to public goods which are often state run or owned in countries with a flourishing private sector. The principled opposition to private sector involvement in certain services may have better or worse justifications, but it doesn’t amount to a plan to fundamentally reorganise society, in the way that many socialists in the 20th century did advocate. 

Perhaps for this reason the 'radical' left has actually been quite open to liberal economics. Examples of this might be opposition to austerity framed in terms of standard macro economic arguments, or an openness to carbon taxes as a means of reducing emissions. Certainly, there are certain aspects of a left wing agenda that amount to a challenge of existing power (eg a greater role for collective bargaining in wages). But for the most part, and perhaps even here, this could easily be described as an attempt to make capitalism work better, whilst protecting the vulnerable from its excesses. This desire to conserve and build on existing gains might contrast nicely with the destructiveness of the Conservative Party, and might well be a better pitch to the wider electorate than calls for radicalism, or use of outdated vocabulary.

Consciousness and causation

Few, if any, problems in philosophy seem as mystifying as the ‘hard’ problem of consciousness. How is that certain entities in the universe have this magical property of being able to perceive, think and experience? And where, in this picture, do we fit experience is ‘like’, how the taste of apple juice differs from dread of the unknown? The problem is not helped by the tendency to start introspectively. If we forget about the strangeness of our own experience for a moment, and examine instead how consciousness functions in the world, we might start to get a clearer picture. In particular, I think three points stand out.  The first is that consciousness is real, and it interacts with the world causally. The second is that our knowledge of consciousness is not simply drawn from introspection: we see evidence for consciousness in others in our everyday lives, all the time, and it plays a crucial role in our lives, both in explaining phenomena and setting accurate expectations. The third is that the causal function of consciousness is not independent from the qualitative properties of experience: what it’s like is intimately connected with what it does. 

The first point I want to make is a purely conceptual one. Perception presupposes that consciousness is causally embedded in the world. We can’t say we have seen something without believing that the thing we have seen has caused the perception of sight (in this instant reflected a light source into the retina). A similar sensation that is not brought about causally in this way we would call illusory (a mirage, a hallucination, a dream etc). For perception to be useful, this process itself has to be causal (it is conceptually possible that that perception is epiphenomenal, i.e not useful, but this seems improbable: more on this later). It has to have some impact on future actions or dispositions, if nothing else our memory. Every day experience seems to suggest this is the case, or at least it is very much part of our everyday descriptions of perception that it is (“I remember seeing the sunrise”, “I disagree with what you just said” etc etc). At the very least, it seems an inescapable part of life to live as ifcertain mental events, perceptual or otherwise, are causally significant. I cannot decide which train to take to work if I think that my thought process has no impact on events in the world. In the particular case of perception, what counts as perceiving something seems to be about the propriety of mental events to antecedent conditions, given the causal significance of the mental events. I perceive something if a particular mental experience associated with x occurs when x is the case, and that mental experience causes me to have the true belief that x, or respond in some useful way to x. 

We see evidence of the consciousness of others all the time. Our expectations and descriptions of their behaviour would make no sense if this were not the case. If you arrange to meet with a friend, they arrive at a particular place and time because they have decided to do so. Perhaps they are late because their clock displayed the wrong time, and they falsely  believed it was earlier that it was, or they misjudged how long it would take to walk from A to B. Examples like this are endless, and they are not easily replaced by accounts which do not allow for conscious agents. Imagine trying to predict the position of this friend purely by thinking about velocity, acceleration and displacement: even when such a description is possible (as it sometimes is), it could never hope to account for the fact that they have arrived at 11:04 near the bus stop, because 11:04 is ‘roughly 11:00’, and here is near enough to the bus stop for you to find me. 

As it happens, we actually have remarkably rich and accurate expectations of the behaviours of others as conscious agents. We are able to expect that people may be our friends, or partners, might be hostile to us, might be our boss at work, might give us parking fines if we park in the wrong place etc etc. All of these expectations seem to presuppose consciousness, in that they expect people to respond in a way that is situationally appropriate and specific in a way that often requires conscious perception.  Think of being arrested because a police officer believes you are behaving in a drunk and disorderly fashion. Or a shop that is particularly busy because there is a New Year’s sale. Or even taking a contrarian philosophical position and expecting angry disagreement. A huge part of the way we make sense of the world around involves thinking in terms of the expected behaviours of conscious agents.

This is even clearer when we think about emergent social phenomena, like money, schools and political institutions. A piece of paper with a picture of the Queen on it is money because people think it is. It has value because people take it to have value. Trump is the President of the United States because he is held to be, and millions of people putting crosses on pieces of paper (or pulling levers on machines) is part of a process called ‘voting in an election’. Between 1939 and 1945, the behaviour of tens of millions was part of some large social process called ‘being at war’. These phenomena are all quite comprehensible if we see them as emergent behaviours of large groups of agents.

Could these behaviours be equally possible for non-conscious agents? Perhaps, but for the time being, we could make no sense of them and would have no idea what to expect to happen in the world unless we were to say that things occurred ‘as if the Earth were inhabited by 7 billion conscious human beings’. And to think that the world might be so constituted that by extraordinary coincidence people behave in exactly the way they would if they were conscious, but in fact are not, through mechanisms that make no sense to us, while not logically impossible, would be a very strange belief to entertain indeed. 

Even if we accepted that consciousness was a real phenomenon, might we at some point in the future develop explanatory frameworks for human behaviour that make it redundant? Perhaps when it comes to certain behaviours (some things we think of as conscious decisions might turn out not to be, we are often deluded about how much about a situation we are really perceiving etc). But the difficulty remains that our behaviour is often circumstantially specific, where what counts as a given set of circumstances is itself reliant on the act of interpretation and on human volitions and expectations (I am annoyed because someone is ‘late’). As a practical matter, we could certainly never have the sufficient data to predict behaviour in everyday life. And then we must take into account the fact that conscious perception can be novel. Consciousness allows us to respond to an indefinitely large number of unique, never before described circumstances (and to describe them!) and for this to explain behaviour causally. We can be particularly moved by the sight of a star, and in doing so have our behaviour determined by a system thousands of light years away. We can think differently of a film because we missed the first scene. To do away with consciousness as explanatory would require a set of recursive rules which can account for a similar array of responses, all happening to coincide with conscious experience. 

And why would we have to do so anyway? The key motivation, I think, for attempting to do so, is the idea that seeing consciousness as part of causal chains makes us think that there should be some kind of intuitively satisfying explanation of how something immaterial like perception could arise and interact causally with the ‘material’ world. This is indeed an alluring assumption, and it is difficult not to see consciousness as somehow magical and mysterious. But this might be a misconception of what explanations should seek to do. There is no reason why the universe should be so constituted as to be describable in a way that allows for ‘intuitive’ mechanisms that would follow from how we visualise a problem. And even if we did, why would this make such an account more plausible? Our ability to derive satisfying metaphors that reduce causation to dominoes falling, or things pushing and bumping into one another does not make our descriptions more or less true. A complete causal explanation does not have to allow us to picture the process; being able to do so may be satisfying, and perhaps sometimes help us apply a concept, but it is not logically necessary. A more realistic ambition might be simply to have a description of consciousness that is theoretically comprehensible, i.e we can know what it predicts (in this case, the conditions under which consciousness occurs, how it behaves) and that does not violate other principles we know to be true of the natural world. 

On this last point, we might think that consciousness seems to violate other natural laws, as it seems to require spontaneous behaviour (i.e behaviour which is not determined by the laws of physics). But I think this is a mistake. Belief that consciousness is causally significant does not require consciousness to be random or spontaneous. It can be fully determined by antecedent conditions yet still causally necessary for subsequent events. We might say: a system would behave this way under these conditions, given that it is conscious, and it would be conscious, given what we know about the system, but it would not behave this way if it were not conscious. I think part of the problem might come from the a fallacy surrounding the transitive nature of causation. Typically it is the case that if A caused B and B caused C we can say (more or less usefully) that A caused C. But this does not imply that B did not cause C, that B’s causing of C was independent of A or that A’s causing of C was independent of B. If it rains on a cold night, the water freezes and the next day I slip on the ice, I may not have slipped were it not for the rain. But the rain only made me slip because it turned to ice.  And the slipperiness of the ice is not a property which exists independently from the arrangement of water particles in a crystalline structure at a certain temperature, but nor does a description of the latter get rid of the former. 

But how does consciousness ‘do work causally’? Or, put differently, how can the consciousness of an organism explain its behaviours? Certainly there is a lot we don’t know yet. One starting point might be that the phenomenal content (what experience is ‘like’) does not seem to be as separate to what an experience ‘does’ as some might suggest. It is not the case that what it is ‘like’ to experience pain is unrelated to how we behave when we are in pain. Pain, after all, is (generally!) something unpleasant we try to avoid. Perhaps we cannot describe the difference between the experience of seeing something blue to experiencing something red, but we can say that these are different experiences. That is, after all, what allows us to differentiate between the colours of different things (it can, correspondingly, be determined observationally that someone is colour blind, as they are unable to differentiate between colours). If, as earlier suggested, what makes something count as perception is the functional significance of the mental experience of perception, ie what it causes us to do, believe, remember etc, and whether this is appropriate to the antecedent conditions which brought this experience about, the question then seems to be: how does the phenomenal content of experience (what it is like) relate to its function (what it does). Might it be that certain types of experience, when brought about in the right conditions, are capable of generating useful responses, and others aren’t? And how does the function of a conscious experience affect what we might look for in the system from which it arises? If, for example, some consciousness is computational, we might look for a physical system capable of carrying out computations, or giving rise to a phenomenon capable of doing so.

Is consciousness identical to neurological states, a property of a physiological system, or something separate which is ‘brought about’ by physiological systems? I’m not sure there’s as much difference between these descriptions as sometimes is made out. Consciousness  isn’t a separate entity (as John Searle once remarked “it’s not a juice squirted out by the brain”), and it’s not clear what it means to say it is spatially located, other than saying that its causal interactions are specially located. We can call it a property of a system if we like, so long as we remember that in doing so this property is taken to be something which is likely to explain the behaviour of the system (in the same way that liquid water behaves a certain way because it is fluid, ice because it is a solid etc). We can call it something ‘brought about by a system’, so long as we remember that this does not imply a separately existing spatial entity. 

Hopefully these few paragraphs might give some clarity to how we might think about this problem. At the very least, I hope they aren’t entirely trivial. I don’t wish to assert that these tentative answers are absolutely necessary. While perception may require consciousness to be brought about causally, how do we know we aren’t perceiving at all? And while reference to conscious agents might be important for making sense of the world, how do we know the world is structured in a predictable way, at all? These objections are of course all possible, but in the same way it is possible that the world is fundamentally incomprehensible, that the sun might not rise tomorrow, that we might all be brains in vats etc etc. We can still entertain doubt about the existence and nature of consciousness in the same way we can entertain radical scepticism about existence, in so far as we do not find answers to that scepticism satisfying. But we must not confuse this kind of radical scepticism with an observation specific to consciousness or the mind-body problem. And while the account outlined does not allow us to intuitively ‘get’ how this strange property could be true of physical systems, it does, at least, mean we do not have to doubt the every day phenomena that life does not allow us to seriously call into question. It is, perhaps, an attempt at answering a the following question: if, as may or may not be the case, our concepts of knowledge, perception and belief do roughly work, and if these concepts are at work in accounting for behaviour, how, in the abstract, do these experiences relate to the things they are supposed to refer to?

Dream Catchers

These days, most people tend to dismiss the Dream Catchers as a kind of sad cult.  Certainly, their rituals, strange terminology and mystical beliefs about the true self being unleashed only in sleep (that of 'perfect autonomous creation, uninhibited by the boundaries of physicality') are eerie, to say the least. But it's easy to forget that underlying the brief popularity of this movement was a sound argument. We spend a very large portion of our lives asleep, and a substantial portion of that in something akin to a conscious state, so why should this not be thought of as an equally valid and important part of lived experience?

Improving our dreams, so the idea goes, is as much an improvement of our lives as improving waking reality. You may have a great job, a happy family life etc etc but what good is any of that if you spend several hours a day being haunted by monsters, appearing naked at work in front of colleagues, or constantly losing and regaining your teeth? The 2010s saw a surge in interest in improving your sleep as a way of feeling better while awake, but it wasn’t until the next decade that interest grew in improving sleep for its own sake. A huge literature emerged on 'tips and techniques' to improve your dreams, there were endless talkshow debates, pages of magazines were filled, the British tabloids showing a particular interest in the subject. Most of this we of course now recognise as pseudoscientific junk, but it had tremendous purchase at the time. So much so that there was a crackdown by HMRC on dream therapists, once it was realised how much revenue was being lost to those who weren't paying their taxes properly. "Nobody dreams about VAT", a well known government minister once quipped. 

But for all the junk science and spurious, unregulated medical supplements, it's easy to see why so many were taken in by the idea that dreams mattered. In an age of increasing economic inequality, to many there was something emancipatory to this idea: perhaps there may be those with better careers, who own rather than rent, who have more fulfilling romantic encounters, but no waking money or good fortune can buy a pleasant dream. 

Some saw a sinister side to this early on. If, so the idea went, we gave equal weight to our waking and sleeping lives, might we simply lose focus on the present? Or was there something deeply regressive about this new interest in dreams? Might they come function in much the same way Nietzsche described Christianity, a system of morality where we focus not on the cruelties and injustices of the physical world, but instead take refuge in something else, something beyond? 

The irony of all of this was that it turned out that a good waking life was the only reliable predictor of a happy dreamer anyway. On this question all serious statistical studies were unanimous. The wealthier had better dreams and dramatically fewer nightmares, those who were worse off, particularly those in precarious work situations had a far worse night's sleep. As one columnist for the New Statesman put it: "inequalities in the afternoon reproduce themselves at midnight".

Certainly, only a small minority ever became fully fledged Dream Catchers, even at the zenith of public interest in the subject as a whole. Their asceticism, endless meditation and frankly bizarre ideas about sexuality were off putting to most. But it's easy to forget that their emergence was part of a quite widespread, if brief, fad for a novel kind of self improvement.
