I was under the impression that the federal government had nationalized the private student loan industry. This happened when the terms of the note made it impossible for anyone to default on their note. It is now a debt that will follow you to your grave if you do not satisfy the terms. Indentured servitude at least had a term limit. I believe the proper analogy would be self sold into slavery with an option to redeem yourself. It is easier to break an enlistment contract than the terms of a student loan today.
For those terms, the benefit should be very great indeed and I am fairly certain that most degrees earned today do not meet the standard.
