How many non-government job openings can you find for any of the worthless degrees I listed?
None of those degrees are required to serve coffee, French fries, or beer, or to drive taxis, or any other jobs where these useless degree holders end up.
Sorry, but I prefer to have the individual make the decision about what kind of education they want, not the government.
You might have a point if you could show that certain majors defaulted on their loans at a higher rate, and that was the critereon the government used to decide to guarantee the loan or not, but I sense you're just basing it on your idea of what's a worthy field of study.
As long as the government is guaranteeing loans they should be neutral as to major. Again, who decides what majors are "government approved"?
