A thought to keep in mind as you read this - what happens to the already overburdened graduate whose job gets outsourced, and then can't find another because he's deemed "overqualified" for the low skilled, low wage jobs available?
Answer: Look up "capitalization of interest" and then note that one can't erase student loan debt by declaring bankruptcy. What will result will be the mathematical equivalent of charging compound interest on a loan that the graduate has been deprived of the means of repaying.
