The days of society believing that educating its students is a good thing is long gone (except of course when CEOs are trying to justify offshoring jobs!

). Student loans are now just another commercial endeavor, and as a result, their only purpose is to make money for the vendor. As students have no credit worthiness, they normally get loan-shark rates.
14% is actually pretty good for an unsecured, no-credit-record loan, although I haven't been in the market (and won't be) for a student loan in quite a while.
Good luck though!
