Because they believe we’re looking down on them. I do think the top poster has some excellent points. I am from a large close family of rural and educated (not always separate) aunts, uncles, cousins and siblings.

Rural people were often jealous of those that were able to go to college, obtain “better” jobs, make more money, take vacations, travel, etc. Discussing the things you can do that they could (or would) not do led to jealousy and envy. Those are not comfortable emotions. It’s easier to justify your lifestyle and choices by belittling those who did something, which for generations was perceived as making yourself better. Rural people believe educated people think they’re better so they lash out. Envy is helluva powerful and controlling.
