It's not that the government spends too LITTLE money - it's because it spends too MUCH without any in the form of cheap student loans with no risk based pricing.
Any 18 year old with no credit history can go and and take out over a $200k of student loans ($57,500 / year) from the government, without any regards to school or risk.
Barely graduated high school and majoring in underwater basketweaving at BoneHead U? As long as it's an "accredited school" (a sham process in and of itself), here's your money - at 3.5% interest! Nothing secured against the loan, no evaluation of your ability to repay, nothing - just free money with the not-so-insignificant fact that these loans are mostly non-dischargeable in bankruptcy or in some cases even death[1]
Majoring in computer science at Stanford? Here's the same loan at the same terms!
Now tell me which student is more likely to default and which is the better risk?
It's ABSOLUTELY because loans are underwritten by the US government willy-nilly in the name of "education for all" that we're in this mess, with universities building movie theaters and lazy rivers[2] at taxpayer expense.
It's a trillion dollar bubble waiting to pop.
