I think the interest rates on student loans should be a low as possible and run through the government, not banks. Banks should not be profiting from this. 6.8% is very high Digs, higher than the current mortgage rates too.
I agree for more funding for grad schools. There are many professions, for instance, teaching, that require a masters or higher, in order to be gainfully employed or keep employed.
The debt incurred by our college students is bracing. Yes they will ultimately benefit from higher paying jobs, but how terrible to have such an anchor around their necks when they are just starting out in life.
