Unfortunately we live in a world where some of the necessities of life are disparaged and sometimes even criminalised. Carbon is perhaps the life-giving "villain" highest in the public eye right now, but the free market, without which most of us would be living in squalor and misery, or even be dead, cannot be far behind.
In a nutshell, the free market is one of the necessities for wealth and happiness, but in the popular perception two things go very badly wrong:
The former problem means that free markets can be, and perhaps always have been, implemented badly so that a range of corruptions can be indulged in, often perfectly legally but without a shred of morals. The latter problem means that many or most who concern themselves with these issues, and who have the best and finest intentions, turn against the free market and trading in their entirety, and therefore never take part in any discussion to fix the problems with how free markets are actually implemented.
Hayek was one of the key advocates for free markets. His central explanation of why they work is this: for an entire complex society to take, on the whole, the best and most profitable actions (such as to use less resources, create better products, transport goods most efficiently, and so on), the knowledge of millions of individuals is needed. For example, I might know the cheapest way to move things from X to Y; you might know how to make something cheaply at X. Our knowledge combined might make a better product available to a purchaser at Y. So should someone at Y hire me to do shipment, you to make the product, and so on? Maybe other people have a way to make the product at Z and ship it to Y. Which plan optimises the Earth's resources? The answer is that in a free market, prices tell the buyer at Y whose product to buy. If one or the other group of suppliers cannot match the best price, they will get no buyers. If the prices reflect true costs, and if all inputs (including damage to the environment) are costed, then a free market results in the least damaging and most efficient way to obtain the product.
I recall stories on television around the time of the Soviet breakup showing horrifying environmental damage throughout the former Soviet Union, due to badly planned industrial activities in the era of central planning. Hayek's point is that central planners, no matter how clever, how well supplied with supercomputers or you-name-it, cannot compete in making decisions with millions of decision makers informed by prices set in a free market. The point is that prices convey to us information in a distilled form that came from the knowledge of hundreds or thousands (or millions) of other people. Choosing the best price automatically chooses the best set of actions by all those people whose individual knowledge we could never hope to digest and make sense of. Central planners will always fail in comparison to a free market.
So what goes wrong? Why are so many people opposed to free market economies? Are they simply stupid?
I do not believe so. Things definitely can and do go wrong in free markets, things Hayek doesn't account for, and in some cases these things are nearly always allowed to go wrong; so it is an understandable error to blame the basic concept of the free market, rather than the distortions that are in practice almost universal.
Those who are familiar with any system that organises itself according to basic mathematical principles (which is most of them) will know that typically, systems have what might be termed a 'relaxation time'. If you disturb a system, it takes a while to settle down to a new equilibrium point. Alternatively, it might not settle; perhaps it orbits an 'attractor'. An example of this is national economies. The boom and bust cycle of normal economic activity can be shown to cycle around a relatively stable point. When governments intervene to 'stimulate the economy' or 'reign in inflation', all they are really doing is speeding up or slowing down the natural cycle. A good explanation of this is found in Ormerod's book, The Death of Economics. I'll explain this in more detail another time.
Bearing this in mind, one problem with free markets that Hayek misses (or, at least, I cannot find properly discussed in the maybe half dozen of his book I have read) is that prices themselves do not respond instantaneously to the costs that drive them.
For example, say we are making widgets out of zoopers imported from Wijistan. Maybe a hurricane puts the zooper production line in Wijistan out of action for a while, or maybe shipping charges increase. It will take time for these costs to flow through to our production line. Sure, we will try to anticipate problems (and some people are better at this than others) but nevertheless our pricing on widgets will trail by some time the cost changes for zoopers and shipping.
The effect of this is to open a 'market' for forecasters (or guessers) who will try to anticipate our troubles and buy or sell shares, or maybe short sell or something even more complicated, and 'make a killing'. But what are they really doing? They are trying, in a complex way, to trick someone else into selling them something, or buying something from them, at a price at which they would not buy or sell if they knew all the information the forecasters know. Is this a disguised form of fraud? We can argue about that, but for sure this is the kind of thing that is considered mean and nasty, and gives markets a bad name. After all, do nice people really try to trick others into handing over their money?
So here's the problem: the free market tracks costs and informs us of them by way of prices, but the process has an inherent delay. Due to this delay and other problems, a huge market has arisen whose main activity is trying to take advantage of others' relative lack of knowledge; this activity sometimes swamps the activity of investing in enterprises for their productive earning capacity. This is one reason why, rightly so, many consider stock markets and so on to be 'nasty'. It is also one reason why 'economic rationalism' isn't rational.
So where is this taking us? I believe we need, as a society, to take a good hard look at the free market, and introduce rules whose purpose is to make it work properly to reflect costs in the resulting prices, and to discourage all forms of speculation except that about future productivity (that is, investing because of long-term profitability rather than short-term fluctuations).
Here is one idea, which may have many flaws and need big reworking, but which illustrates the kind of thing we need to think about. How about the income tax on stock trade profits depending on the time a stock has been held? If I sell more than a year, say, after I buy, I pay the normal tax rate, but if I sell within a day of buying, I pay 100% tax (making the trade pointless), and so on proportionally for times in between a day and a year. That means that, to get the best return on a profitable trade, I need to predict that a company will do a profitable job a year ahead. That should be far enough out to cover the typical relaxation time for changes in market conditions, and thus minimise the benefit of smart forecasting and maximise benefit from a proper understanding of a business and its potential for producing wealth.
Hayek's insight was the inevitable inefficiencies of any kind of command economy - which everything except a free market ultimately boils down to. Loss of control of the individual's own resources in favour of central planning, however high-minded in intention, however altruistic in conception, ultimately propels the worst of people into the positions of control. How many times must we see the people being expected to 'give up selfishness' and cede their powers to the 'Great Leader' who will never use that power as well as the average of all the many ordinary folk going about leading normal, decent lives?
Hayek's oversight was thinking that the market can run according to perfect rational theory. Give the avaricious half a chance and they will use any system to syphon away the wealth of those who think in terms of making wealth by production rather than manipulation - and yet production (including non-tangible production such as teaching, research, services, etc.) is ultimately where all wealth comes from! Those who typically oppose free markets usually understand this. The way forward must be something that brings these seemingly contrary insights into harmony.
