I could understand allowing borrowing for engineering and medical degrees to continue at 100-percent. Beyond that, I wouldn’t allow a yearly amount to go past $12,000. A lot of these dimwits haven’t grasped the out-of-state cost difference. If you toss in degrees which are useless and will never get you more than $40,000 a year in salary, then why loan out $100,000 for a one-star marginal degree.
In-state tuition at one of our state universities $12,000 per year for an undergraduate degree. Housing costs the same. So by your metric no one is going to college unless they can pony up for it.
