I'm not trying to add water to an oil fire but Lenin himself categorized the USSR as state capitalist. Correct me if I'm wrong, but didn't he and his people consider state capitalism to be a necessary step towards communism?

The state capitalism, which is one of the principal aspects of the New Economic Policy, is, under Soviet power, a form of capitalism that is deliberately permitted and restricted by the working class. Our state capitalism differs essentially from the state capitalism in countries that have bourgeois governments in that the state with us is represented not by the bourgeoisie, but by the proletariat, who has succeeded in winning the full confidence of the peasantry. Unfortunately, the introduction of state capitalism with us is not proceeding as quickly as we would like it. For example, so far we have not had a single important concession, and without foreign capital to help develop our economy, the latter’s quick rehabilitation is inconceivable.
