Granted, I went to school in Canada where tuition is much lower, but so are the scholarships (my $10,000 out of high school, versus my friends that were getting $50,000 for Ivy league schools with the same grades).
However, I got student loans for the years that I needed them. They were spent on tuition, books, and housing. I did not buy a car. I did not spend it on alcohol. I did not spend it on a new computer, though I wanted one. I graduated with ~$20,000 in student loan debt. I paid it off in a year. That was two degrees and 6.5 years of schooling at a university, not a college, that is reasonably-well recognized internationally.
My wife did the same things, but as she was in a nursing program which much higher tuition and books and didn't manage to get the same caliber of summer jobs, she was ~$45,000 in debt at the end of her degree. She paid hers off at the same time I did.
I don't have a lot of sympathy for people who whine about their student loan debt. I've seen the things people blow student loan money on, and a hell of a lot of them could get by with a lot less money in loans if they controlled their spending. A part time job helps too. I know there are students out there that genuinely need to get large loans to live off of, but most don't.
There is also the tax break that comes from paying off loans as slowly as possible which some people see as an incentive to drag out the process. If they did the math, they wouldn't - in many places in Canada, loan interest is set at PRIME +2.5%.
To compare, I paid off the final loan total with a lump sum, that also pays off the initial interest when it came out of interest free status. My younger brother, who did one degree and graduated university before me with an engineering degree that gave him a job making $55,000+/yr straight out of post-secondary, did not. I'm student debt free, and he's going to be making the minimum loan payments for the next 15 years.
That's another point - 5 years after finishing my last schooling, the only debt I have is my mortgage. My wife and I have a lot of older belongings, we don't drive fancy cars, and we make decent wages, but the biggest contributor is financial prudence. A lot of younger people don't have it.
A large part of student debt problems is financial illiteracy, not the school system.
