Making money cannot be an end in itself – at least for anyone not suffering from acute mental disorder. To say that my purpose in life is to make more and more money is like saying that my aim in eating is to get fatter and fatter. And what is true of individuals is also true of societies. Making money cannot be the permanent business of humanity, for the simple reason that there is nothing to do with money except spend it. And we cannot just go on spending. There will come a point where we will be satiated or disgusted or both. Or will we?
