"I've got norovirus"
More like "I had norovirus a month ago but now I've got covid." The Soviet Union doesn't matter because it doesn't exist anymore and China is a capitalist country for a while now. The problem is capitalism because it's the world system now. There are countless counter examples so the problem isn't humanity. Bolshevism isn't a counter examples (because it wasn't any better) but neither is it the problem because it doesn't exist anymore. Neither is the Roman Empire.
