Landslides can turn one machine out and put another in; revolutions sometimes abolish a particular machine altogether. The democratic revolution set up two alternating machines, each of which in the course of a few years reaps the advantage from the mistakes of the other. But nowhere does the machine disappear. Nowhere is the idyllic theory of democracy realized. Certainly not in trades unions, nor in socialist parties, nor in communist governments. There is an inner circle, surrounded by concentric circles which fade out gradually into the disinterested or uninterested rank and file.
