Who the fuck else should we blame beside corporations and economic leaders for economic inequality?

If you accept the existence of a capitalist system (and I'm not sure we have a better option at the moment), then it's fully expected that economic leaders and corporations will try to maximise inequality because, that's their entire purpose and yardstick of success. There's no point blaming them, they're not about to change. Rather, the leaders themselves should be to blame for not implementing proper guidelines and wealth-redistribution systems.
