Humans aren't really built for communism on a large scale either. We are tribal, capitalism gets around that with incentive and greedy individual reward for doing something that generates social improvement at scale (nation-state) level--trade, commerce, interaction, communication. Communism, Marxism will never provide that. You either have to use the carrot (capitalism) or the stick (despotism) at scale to get results. Communism (real communism) fails beyond a few hundred (may only tens) of souls, again we didn't evolve for that,
