Are dumb people, in fact, easier to control?

I have seen a lot of smart people in thrall of ideologies that could be used to manipulate them left and right at will. Meanwhile, true morons tend to be unpredictably chaotic.

Yea. Dumb people are lower class and uneducated. Give them a few bonuses and they’ll happily shut up.

This explains why governments never subsidize universities

Indian government universities are subsidized but difficult to get into and don’t get you on an automatic path to leaving for a better destination.

Most do enough to keep their people from revolting.
