Actually, I don't have numbers on China, but in USSR throughout most of properly recorded economic history 10% of the wealthiest people owned about 20% of all money in the country, give or take depending on the year. In modern Russia, it is about 65% from what I remember, and that doesn't include offshore funds of the oligarchs.

Also, they weren't fascist by any definition. Authoritarian - yes. Fascist - no.

Not arguing for anything here, both countries could be way better, but your claims are wrong.
