I agree that gov backed student loans are making the situation worse but removing them would be disastrous. Maybe and I can't prove this but maybe, if the gov was the sole lender, they could pressure universities into reducing tuition?
Scary thing is that the government will be the sole backer of educational loans. We all know how slow and antiquated they operate. I don't know if this is going to be a good or bad thing for the economy.
The type of pressure universities will get from the government will only be the kind of pressure that is politically expedient. We have enough affirmative action university system as it is.
