It is a mixed economy—such as the semi-socialist or semi-fascist variety we have today—that protects the non-productive rich by freezing a society on a given level of development, by freezing people into classes and castes and making it increasingly more difficult for men to rise or fall or move from one caste to another; so that whoever inherited a fortune before the freeze can keep it with little fear of competition, like an heir in a feudal society.
