Because in [Lenin's] eyes the workers
were only workers and not also customers, he believed they were already slaves under capitalism, and that one did not change their status
when nationalizing all plants and shops.
Socialism substitutes the sovereignty of a dictator, or committee of dictators, for the sovereignty of the consumers. Along with the economic sovereignty of the citizens disappears also their political sovereignty. To the unique production plan that annuls any planning on the part of the consumers corresponds in the constitutional sphere the one party principle that deprives the citizens of any opportunity to plan the course of public affairs. Freedom is indivisible. He who has not the faculty to choose among various brands of canned food or soap, is also deprived of the power to
choose between various political parties and programs and to elect the officeholders. He is no longer a man; he becomes a pawn in the hands of the supreme social engineer. Even his freedom to rear progeny will be taken
away by eugenics.
