Not in a great man theory sort of way, but who would you say is the worst living human today? Sometimes I get too bogged down with thinking about our issues as systematic and forget that all policy has someone signing off on it and that got me thinking and I've arrived at Bill Gates. With his work in Africa, how he ruined computers for the world, and the Epstein ties I'd say he's gotta at least be up there.
Gates basically controls the WHO as the Gates foundation is one of their biggest benefactors, almost spending as much as the U.S. government. If you want to work in global health and run afoul of capitalist interests you're going to have a bad time.
