I disagree that colleges and universities should be treated as places to learn a trade. Soft skills, yes, but I stand by my own liberal arts education as the best way to learn *how* to think. Internships have proliferated because they’ve been allowed to for various reason (many of which I’ve outlined)— there’s no single reason. Labor, be it paid or not, is a multi-pronged issue.
Can you be more specific regarding “fields that don’t pay”?
