Because for colleges to grow, they had to admit more people even though there are not enough good jobs available for the college educated and mostly indebted. This is the fault of the colleges for charging so much, and promising a better future when no such future was possible for the majority of their students. The students are justifiably pissed for getting rugged. So in order to avoid getting blamed, the colleges indoctrinate them to believe it's the man keeping them down, that capitalism is unfair, etc. When really they fucked their own students with a bad deal.
