To me , most college university major are just luxury, and you should only go there if you have fine finances.
It's has been proved that a college degree in the right major is the best investment you can do, even with the big loans you have to take.
The problem with people not being able to payout their loans is because they did not took a good choice in major. And why should my taxes go into someone spending their time in a liberal arts major? or anyother with little or no relevance to the market? Those kind of loans are never pay, and yes, if it's free it's a loan as well, the state will use the tax money to fund these students, expecting to get some bigger tax money later when they graduate. Well, bad majors won't find well paid jobs, the tax money wasn't well invested.
Maybe I'm just a sad adult, that just sees everything around money/market value. Maybe I should have spend my college years in some place where college was "free" perfecting my art skills. Now I pay for my art classes after work... What an absurd idea, to pay for an hobby, rather than having taxpayers funding some years into my hobby research.
edit: I'm talking mainly about tuition, things like access to classes references/books/material, it's ridiculous to be paid, as the ones that wrote those were already paid to do it, and a lot of it, done with research payed by taxpayers
