Mises’s classic essay on the interventionists who emphasize that they plan to retain private ownership of the means of production, entrepreneurship and market exchange. But, they go on to say, it is peremptory to prevent these capitalist institutions from spreading havoc and unfairly exploiting the majority of people. It is the duty of government to restrain, by orders and prohibitions, the greed of the propertied classes lest their acquisitiveness harm the poorer classes. Unhampered or laissez-faire capitalism is an evil. But in order to eliminate its evils, there is no need to abolish capitalism entirely. It is possible to improve the capitalist system by government interference with the actions of the capitalists and entrepreneurs. Such government regulation and regimentation of business is the only method to keep off totalitarian socialism and to salvage those features of capitalism which are worth preserving. On the ground of this philosophy, the interventionists advocate a galaxy of various measures.
