"One of the fairly interesting things about money is that it makes certain things possible that wouldn't be possible otherwise - it doesn't make them inevitable. Hence the strange blindness of economists to what would actually happen when one does exchange things if there isn't money in such contexts."

Why shouldn't I be interested in politics? That is to say, what blindness, what deafness, what density of ideology would have to weigh me down to prevent me from being interested in what is probably the most crucial subject to our existence, that is to say the society in which we live, the economic relations within which it functions, and the system of power which defines the regular forms and the regular permissions and prohibitions of our conduct. The essence of our life consists, after all, of the political functioning of the society in which we find ourselves.
