In fact, I would say that this seems to be an author's issue, because the same thing happened at FOM: Soviet communism degenerated surprisingly quickly into a genocidal ideology that only differed from Nazism in the emblem they used on the flag.
I would argue that that isn't really an issue, but more an objectuve fact: just like Nazism, Communism voews certain groups of people as inherently evil and once these people are "removed" everything will be perfect.
So whenever the promised utopia doesn't arrive, you just expand the definition for "enemy of the state" and purhe them as well, using them as scapegoats, ehich very quickly becomes genocidal.
And exterminating a class is as much genocide as exterminating a race.
It could seriously discredit neoliberalism but I might be too optimistic.
Sadly this won't occur. There are simply so many reasons for Russia to fall, that each group can blame the others responsible.
Make no mistake, the disasterous transition from Communism to Capitalism certainly played a role. But the Neoliberals will blame the Communists, the Communists the Fascists, the Fascists the ethnic minorities, and round and round we go.
