I was in the USSR during its collapse and can tell you that this was the merit of a single person -Gorbachev. He shook the system so hard (in noble desire to make it more human-oriented: democracy, market, multiparty system, freedom of all kind, etc) that after 5 years the old administrative system could no longer function smoothly and practically collapsed.

Unfortunately, the new system has not been built yet (even now), so many people today in Russia feel that actually pre-Gorbachev time was not as bad as today's "wild wild east" without "bright light at the end of tunnel" at sight yet. So, they demand more stability, elderly/youth coverage, better order on streets, less freedom for drug dealers and to limit power of greed (money) leading to all kind of corruption.

I think, China is doing right: reforms step-by-step, not by revolution (complete destruction of old system) but by evolution (rebuilding and preserving what is good).

Capitalism is extreme, and optimal order is actually a mixture of best from both capitalism and communism (communism utopia is actually Christ's idea of all people obeying commandments - but by biological/genetic reason it does not work).
