You can’t now, because in the risk free lending environment created by outlawing the discharge of student debt in bankruptcy the resultant flood of money into colleges has driven the price up to where you can’t pay your way through on summer and part time jobs.
It is also the reason there are a myriad of worthless majors available now, wymens studies, underwater fire prevention, refuse basket odor control, etc... all exist from being created to soak up the essentially free cash sloshing around from risk free lending.
Good analysis.
And of course Big Education (profs and admins) contributes substantially to Democrats. Another reason to flow big bucks to them.
