If universities are such socialist institutions why do they cost so much to attend? How do the Koch brothers get to sink so much money into so many business schools?
Because, for the most part, professors and college administrators have not yet bridged the gap that is the logical contradiction between reaping the benefits of our current free market (for example, their lofty salaries, paid leave of absences every 3 to 6 years, pensions, incremental pay increases, right to unionize, etc.) and their rhetorical rejection of that system.
They want the state to pay for education because it ensures their own long term career protection. This has little to do with any real humanitarian views these Marxist profs actually cultivate into integral day-to-day life convictions.
They're the most pampered of the privileged elite, and yet they write monographs decrying the privileged elite. The only reason they get away with it is because undergraduates are largely too ignorant to know any better and because the parents who are sending their kids off to these schools have yet to actually discover what's going on there.
But the bubble is bursting as centrists, classic liberals, and intellectual conservatives are pushing back and exposing the deceptions for what they are. As a result, the humanities are being obliterated right now with hiring and salary freezes. Further, the Marxist profs are sounding the horn louder than ever before by calling for free education.
After all, if they manage to shift the paradigm over to tax-funded college education, their place of privilege in the ivory tower is protected.
It's all about self-benefit for the vast majority of them. But calling it for what it is would be disastrous, so attacking the system (WASPS, western "constructs" of white privilege, the traditional family unit and the role of the father figure, etc.) makes for a potential avenue of enlisting enough young people into their cause to recreate our society with an emphasis on "free education."
Of course, nothing is free, as we know. There's always a massive price to pay when it comes to force-feeding Marxist dogma or even its euphemistic shadow of "democratic socialism."
The 20th Century stands to remind us of such costs, and 100 million body bags and their outlying mass graves quickly remind us of what happens when the state dictates the values and principles of a society.
