The average American doesn't know what capitalism, socialism, communism, or fascism means. They don't know what representative democracy means. They don't know what first past the post means. They don't even know that they have an electoral college let alone its role. The 3 branches of government are largely a mystery. And most Americans are under some kind of impression that the POTUS is some kind of benevolent dictator.
I'm not surprised that someone on twitter thinks capitalism solves poverty.
I mean, it helped bolster rationale for enslaving black people. It's fair to say that capitalism tips the scales, steals your car, and then runs over your neighbor before disappearing with your spouse and your dog/cat.
