The Soviets couldn't plan enough of the economy at the time and running worker wages too close production capacity, especially with opportunist-run factories, created the capitalist-blackmarketeer-gangster class that overthrew the Proletariat through Kruschev, Gorbachev, Yeltsin and now maintains control through Putin.

It could have been saved but it's easy to see why China doesn't want to play with fire like that and would rather have opportunists turn out like Jack Ma rather than Gorbachev and Yeltsin.
