Look at the UK. It wasn't people of different races who drove their systems into the ground. Communism came because people can't make the selfless decision to not vote themselves more money. The poor in England protested for the quality of life which could be only afforded by wealth, and in doing so gave the power to grifters and con men.
The USA's no different. The main difference is that those same con men and grifters played the race card too. We're still stuck with a selfish and uninformed voting population who would sooner believe that the world's ending than that socialism destroys societies.
Our problem isn't much of a race problem. Its entirely a selfishness problem. Young people voting their children's children into poverty.
They think they hacked the system. "My children will never be enslaved to my debt if they're never born in the first place!"
