Put them out of business.
It seems to me that fixing the post secondary system is one of the easier problems to solve.
IMO, the problems intensified when we as a nation elevated education to the level beyond the status of religion in our society. The schools received the status of churches, the professors the status of priests. Tuition, and tuition support from the government, became the equal of donations to a church. The money poured in easily eclipsing the total of all contributions to organized religions. The major universities function now as virtual city states of liberal thought. They hire from within, outsiders need not apply. Their leaders care not one whit for the country as they dwell on their navels.
There are a couple of years of general requirement classes including liberal arts in undergrad programs, and they make it harder for American men to get through the technology programs. The radical leftists had already invaded English and medical departments and some of the programs in the sciences during the 1980s.
Ingenuity doesn’t come from feminized rackets, and learning is a lifelong pursuit. Put them out of business.
