The propaganda of capitalism has also been widly successful. Many people believe in the myth of meritocracy or that somehow markets will solve all problems or that Jeff Bezos having $200 billion instead of $100 billion while Amazon warehouse employees work in dire conditions are all good things. At the same time, very few of those people can define capitalism but will defend it anyway.
There is no fixing the climate crisis without fixing wealth inequality and giving people dignity and hope for the future. And no, I don't mean some communist utopia where everyone has the same (b3cause that's the usual straw man argument people jump to). I simply mean it has to be way less extreme than it is today.
Capitalism created this problem. Capitalism perpetuates this problem. And it won't be solved until you deal with capitalism.
