Education is indeed becoming the dividing line between left and right all over the world. Sadly, it is because the scope of "education" has been expanded to include subjects with no intellectual content.

Mhm, there have always been soft sciences (sorry MBAs).

I agree that education is becoming a major dividing line, but in my opinion that's because the "left" is moving towards elitism, whereas the "right" is slowly embracing populism. "Only dummies vote for the others" is just a snobby way of saying "we lost the working class".

Such as?

safe spaces, gender studies, wokeness certificates, virtue signaling workshops, degrees in conformity & groupthink.

read William Dereshevitz' "Excellent Sheep", it's the best book on the subject.
