The lesson is that the capitalist economy renders some forms of behaviour rational and others irrational. So you had better do what the market mandates or you will be in trouble. Consequently we find ourselves dominated by the market. But what is the market? Simply the accumulated effects of innumerable human decisions about production and consumption. It is, then, our own product. From which it follows that, once more, we have come to be dominated by our own product. And even though it is our own product it is not under our control. Who, for example, wants the stock market to crash? But this happens, from time to time, as an unintended consequence of our own individual actions, each one of which may have seemed perfectly rational in its own terms. The market is like a monster we have accidentally created, but which now comes to rule our lives. As Marx puts it, we experience the ‘complete domination of dead matter over men’ (Colletti 319).
