And the biggest reasons for exploding debt are:
1) The fact that the cost of college has increased at 2-3x the rate of inflation for the past 30 years. This is reflected in the dramatic increase in the number of administrators in colleges and the levels of compensation some (but certainly not all...) professors get - e.g., Liz Warren getting $300,000 to teach one course a semester.
2) The fact that what students used to complete in four years now takes them 5-6 years.
This is further exacerbated by the number of students who get degrees that are uneconomical - i.e., that will not afford them a reasonable livelihood after graduation. An engineering degree, a computer science degree, even a business degree will get you a job where you can pay off your student loans (well, maybe not if you're living in San Francisco...).
A degree in sociology, or ethnic studies or english probably isn't going to get you more than a barrista's job.. Perhaps you should have thought of that when you were choosing courses.
No one is forced to go to college. No one is forced to take out loans. Think before you borrow, and don't expect other people to bail you out._____
