Oof. What happens when a huge chunk of these default because educating everyone doesn't magically create jobs for everyone?
The banks that loaned out all that money will need massive bailouts or else shut down. Let’s be clear, students will NEVER be allowed to default these loans, nor should they. They must either pay it or take their debt to the grave and pass it down to their heirs.
AFAIK, (and I'm a pretty ignorant fellow) debt in America isn't passed down, the creditors just take what they're owed out of a dead person's estate before its divied up by a will. So there could be a big "pop" if a bunch of people with lots of student loan debt and no assets die.
