Most lack intelligence, most teachers are incompetent as well :\ More than half of all the courses at college are BS, and the subjects you think are good, like politics, psychology, sociology, law are all useless - the sciences are a little better and tend to contradict everything that is taught by the liberal marxist bs just down the corridor. Everything is a checklist of answers, just punching in the same old memes, anything that explains the same process in a different symbol is immediately 'wrong'.
Most things should be self taught, college is just a hipster haven for students to look cool and compete over who has the most friends and too busy planning how pissed they're going to get at the weekend. Also, don't know about america, but in the UK, the colleges are full of retards that run down the corridor with their shoes in their mouth screaming NUUUURGHHHH, followed by a frail old social worker who believes onto death that they have the 'right' to a job in society - they might aswell just shoot them and do the job themselves! Education for all.. haha..
