We're now a full generation since the west "won the cold war" and I think it's just now that our "wartime" mentalities we're ready to think past simple binary communism-x-capitalism binaries.
For example, "privatisation." In Russia & parts of the west, privatisation was a major 90s policy.
But like everything else, details can outweigh labels. One privatisation is not like another.
There's a massive difference between encouraging/allowing entrepreneurship, & "selling" state sectors to "private" owners.
I use scare quotes there because the "sales" were generally paid for with state-backed loans and the "private" owners are either multinationals or "oligarchs" as we now know the "private" Russian buyers.
The former is closer to a capitalist ideal, but doesn't affect the "key industries, at least not fast. The latter is instant, but it also involves something approximating giving away a state's wealth for free.
One big hindsight problem Soviet privatisation encountered is a running theme in modern "capitalism:" the failure/inability of states to get value for/from it's owned assets & wealth.
Neither western economies, Soviet ones or post-soviet ones have a tool in their toolbox for this. Norway's oil fund might be the one exception.
