While this is true, there are circumstances that happily reverse this poisonous tendency in this case. These are not undergraduates studying from textbooks. These are mostly doctoral students in the sciences or performance arts. They not only get no general ed indoctrination (they only take courses in their specialty, and these are entirely subordinate to their research or performance), they experience the difference that a mostly honest, mostly free, mostly economically free society makes. Further, successful scientists or performers are often very creative and entrepreneurial. You have to run a lab, or continually market your talent.

what would a state do if voters held a referendum shutting down a state university (or two)?
Just give the university two years to shut down (or go private)
