You should do some reading into complex systems analysis. No one is putting everything on any specific individual. The system we live in acts similarly to a living being. It broadly seeks to exist in perpetuity and will do what it can to see that through. In our societal system the more money you have, the more powerful you are and the powerful implement systems to further expand and entrench their power. They’re benefactors of a violent and corrupt system that runs on exploitation and they have a responsibility to dismantle it. They never will so everyone else needs to do it for them.
