Don't confuse anti-US College with anti-education. The republicans simply don't believe the US colleges teach. Much like the public school systems have been failing our children, the universities in the US have gone bat-shit crazy with the liberal arts. Instead of teaching, they are indoctrinating naive young adults into a moronic social Marxist ideology: safe spaces, trigger warnings, deplatforming everyone they don't like, extreme anti-white cis male sentiment being taught in classrooms. It's not just a single instance, Missou, Yale, Evergreen and in Canada you have the BS going on with Toronto University and Jordan Peterson.
College has never been the only way to become educated. It was just the best/easiest. They no longer are.
Why build up $40k in student loans, earning a degree in XYZ Studies, to find out that you are still only qualified to work at Starbucks.
