"People who believe in Bad Idea lack education in history/critical thinking/economics/whatever.  If they were better educated, people would not believe in Bad Idea.  After all, I am educated, and I do not believe in Bad Idea, so others would be just like me."

I strongly disagree with this notion. I think it overestimates what education can accomplish, and further it begs the question of what exactly is meant by education.  I find these discussions tend to end up somewhere around, "well, if everyone was educated into a Philosopher King, then we wouldn't have these problems."
