"Communism, like any other revealed religion, is largely made up of prophecies. When they fail to come off its clergy simply say that they will be realized later on. Thus, if we have another boom, they will argue that the collapse of capitalism is only postponed. The fact that the greatest booms ever heard of followed Marx's formal prophecy of the downfall of capitalism is already forgotten, just as millions have long since forgotten the early Christian prophecy that the end of the world was at hand. The first Christians accepted postponements as docilely as the Communists of today."
