The Bureaucratic Collectivist/State Capitalist theory says that a new ruling class emerged in the Soviet Union. This class ruled not by ownership, but by control of the meansof production. If this theory were true then by the time the USSR collapsed such a class should have consolidated itself like all such classes and castes by passing on this control to its children. If true then the Godfather of this class should have been the child of some high ranking bureuacrat. What in fact was Mikhail Gorbachev's background.

Ooops his parents were poor peasants, as Wikipedia sets out.

Gorbachev [1]

A similar Google Search or look at the backgrounds of the Soviet Politburo shows a similar lack of conformity of the facts to the theory.

As I said in my blog before The Nature of the Soviet State [2] A Marxist analysis differs from a Sibjectivist analysis in that a Marxist analysis begins with the facts, not with what might be.
