It really isn't.

"Poor, dumb people outbreed rich, smart people and make the whole world dumb" is not real. And the mechanism by which our world harms people is not because everybody involved is an idiot. Executives of corporations that are destroying the environment aren't just doing it because they don't know better. Leaders within the Trump admin and the GOP more broadly are often extremely well educated at top universities. Ignorance does not drive our politics. Resentment does.
