Well that's not fair. In the 90s, not a trace of communism remained in the Soviet Union. There were cooperatives and speculators all around; you could get anything, but on the black market.

If you want to talk about communism in the USSR, then take at least the era of the 60s.

But in general, talking about communism is pointless because no one has managed to build a communist state. And this does not necessarily mean that the ideas of communism are bad, but rather that the builders are simply not good enough.
