I'm torn on the issue... on the one hand, it seems only fair that you should have the bankruptcy option if you're truly desperate.
but on the other hand, I can think of many, many, many people who would take 5-6 years to graduate from a $50,000/year school with a useless major, declare bankruptcy, and just live at home for a couple years waiting for their credit to improve.
This is one huge reason why they stopped them from being dischargable in BK. Many doctors and lawyers were going BK just after graduating.
The problem now is that it's an asymmetrical situation which has caused risk spreads for that debt to flatten while the risk equation has stayed the same. In any normal situation the higher the risk, the higher the rate. However, if you remove risk (dischargeability with .gov backing) you get rid of most of the risk. This has made borrowing cheap and lending even cheaper. It's a money machine for the lenders. That's why they shove as much money at the students as possible. This is one huge reason why you see tuition going up, more cash flooding into the institutions results in inflation.
I woud say that you allow dischargeability but only after 10 years and even then only for a portion, depending on your future ability to repay while your credit score gets utterly fucked for another 10 years. That way high-end professions will have to repay for 1/3 of the loan term, then only be able to discharge a portion, if any, then they can't even touch a house or a car for another 10 years.
I came out of grad school with ~70k in loans, my wife another 50k. I am repaying every fucking penny of them because *I* signed on the dotted line. *I* took out the debt. *I* went to school and knew how much money it was costing. I However, if I could't pay the loans, at all, even if I were working 3 jobs, then I might seek to get relief.
What's ridiculous is coming out of undergrad with 40k in student loans with an art history major. No underwriter should approve of that loan.
