There certainly seems to be class hatred and division behind it. I don't know if there are any rational elements to it like the higher classes having more to lose, or it is purely driven by propaganda from the ruling class to cement their power.

That people are irrational or willfully ignorant about things is not surprising. People can become irrational and blind to truth through their own self-delusions or through propaganda. Being "educated" or having more money doesn't change that.
