What people need to do is their homework. Figure out how much you need to borrow, what your intrest rate will be, and you can easily figure out the payments roughly. You can then look at what the pay is as a CFI, Regional pilot, etc. With proper budgeting you should be able to know if you can pay things off or not. If you can't pay it off then don't get the loan or live with mom and dad until you can pay it off.
Sure crap happens and a lot of times you can renegoiate with your lender. I think you should be able to change your intrest rate and have some of the intrest payments forgiven. If circumstances warrant(layoff, family hardship, etc.)
I have flown with more than one pilot who had parents tell them to just put their flight training multiple CC's(when they we're handing them out like candy) and declare bankruptcy because a lot of the times a bank will just write it off. That is the problem of this entire country. People we're roaring drunk on credit and then wanted to be bailed out when they couldn't foot the bill. Not a way society should be, IMO.
