Education is still very much present in Idiocracy (Brawndo blah blah). It's the lack of value in logic and thought process that causes the problem. When people value winning an argument on a logical fallacy, there's a severe issue. Education is oft used as the fallacy itself.
Much like today on all sides of every significant debate. Where the loudest most emotional rise on feelings over logic.
If a person doesn't immensely value learning they're wrong, they exist as part of the problem.
