I don't see the unintended consequences: financial companies asked Congress to write a law for the express purpose of insulating those companies from risk and increasing their profits and the results were that (1) borrowers couldn't discharge debts in bankruptcy, making the financial services companies more money, and (2) increased profitability led to more loans, helping drive up tuition costs increasing the average loan amount and making the financial services companies even more money.

Doesn't seem to be unintended consequences at all.
