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"?
Again, taxpayers should be able to decide how their money is spent or wasted. Little Snowflake does not have the right to demand someone else pay for his/her four-year party while pursuing transgendered art history or psychedelic platitudes.
Individuals already can make the decision about what kind of education they want. They just have no right to demand degrees from taxpayer-funded schools for their idiocy. They have no right to demand taxpayers create a job for their brain-damaged pursuits. They have no right to claim permanent disability payments from taxpayers for their own self-inflicted retardation.
I'd guess you are one of these precious snowflakes.
