Here's what I know. My kid graduated in 2008 and has been paying on his loan since then. He's probably going to be paying on it for another 7 years. That loan was granted by Sallie Mae and guaranteed by the Federal government at 5.4%. That was market rate at the time .
and
In 2010, Congress passed the
Health Care and Education Reconciliation Act of 2010, which eliminated the federally guaranteed loan program known as
Federal Family Education Loan Program (FFELP),
under which banks and companies like Sallie Mae made loans to college students backed by a federal guarantee. As a result, effective July 1, 2010, all federal loans were originated directly by the U.S. Department of Education. Currently, there is no existing government-sponsored entities that provide securitization of student loans.

So as far as who is collecting that interest NOW? I don't know other than Navient (a spinoff of the privately owned Sallie Mae) is "servicing" that loan.
A guaranteed loan at market rate (especially one made by the government) is a rip off.. Having the remainder of that loan paid off at least in part is only reasonable.
And between my son and his wife they pay almost $700 month and will be for a very long time.
