The overwhelming majority of society isn’t intelligent enough for higher education. It would either be wasted on them, they would flunk out, or standards would have to be lowered so low as to make their jobs irrelevant or even harmful.
This is absolutely not true. You don’t have to be some brain genius to learn advanced topics. A lot of it is just studying something you find interesting and engaging. The idea that you have to be some kind of out of normal genius to appreciate art and literature, or study history, isn’t true. Most of the hard part of college is the high stakes score high or fail nature of education. The goal isn’t to teach, the goal is to grade people like cattle so porky knows how reliably they’ll produce profit. Without the profit motive, in a society where the goal of education is to produce education people because that’s a good in and of itself, it doesn’t matter if someone whizzes through school or takes a decade to get their undergraduate. If education isn’t artificially made scarce and hoarded then taking years to get a basic degree is fine. Puttering from discipline to discipline looking for something you jive with is fine.
It has nothing to do with class at all. It has to do with how smart you are. If you’re not smart, you won’t benefit from higher education, certainly post-graduate education. You have to be smart to even get in the door. Try to explain Tsiolkovsky’s rocket equation and Kepler’s laws of orbital mechanics to your average Trump voter. They will end up looking at you slack-jawed, then start screeching about emotions and feelings. The rocket equation doesn’t care how you feel, either you produce enough delta-V and in the correct magnitude and direction, and you get to orbit, or you do not and instead fall back to earth. it’s numbers and math and physics. Racists are well-known for their lack of intelligence. America is full of stupid, scared, fucked up sheep who tune into the Kardashians or reality TV for their enlightenment. Higher education won’t benefit them.
