I have a theory that most people are simply not intelligent enough for college. This is the only time in human history where people have been "required" (there not actually required, I know, but to get a good, well-paying job higher education is a must) to have higher education. I think this is a scam by the schools, colleges, and universities to get people to buy their money.
How interesting is it that a group of businesses all unanimously agree that their product is something that you have to have to make it through life and how as soon as it became a necessity for everyone, they decided to hike up the prices to exorbitant rates. It is simply a Gilded Age style trust that's been formed between most colleges and universities.
