[Quarrel]

I'm not sure the Soviets ultimately ever really tried to make the transition, when confronted with the reality that the ruling dogma that they represented no longer worked, they couldn't handle the collapses in the periphery.

Also see the 'lost years' of the Japanese economy, or the Chinese as they try to make the transition now.

It is terribly hard, but the USSR had their heads well in the sand at that point.
