Contrary to its title, this article does not say that the government will require in-school repayment of student loans. It only says the gov't will offer a tax credit if the student opts to do so.
There's nothing preventing other loans -- they just won't have the federal subsidy.
(If someone's reasons were good for deferring repayment while getting further education -- and thus they're still a good credit risk at prevailing private interest rates -- a private bridge/refinancing option will emerge.)
Non subsidized loans are almost impossible to obtain at anything remotely close to the rate the subsidized loans offer. The best I was offered was 15%. At that point it makes more sense to just not go to school.
Unsecured debt like student loans has incredible risks and the laws in the US aren't very strong in favor of forcing people to repay so a lot choose to just ignore the loans causing them to be even riskier and screwing it for the people who plays fair. Eliminating the subsidy without looking at everything else in play here is dangerous.
Except the subsidy isn't going away -- it's just being limited to the feds' own Department of Education loan program, which will then mea less diversity in process/administration.
I doubt that will mean loan policies become more stingy; being stingy (even when required by a clear-eyed cost-benefit analysis) is not what the feds are good at.
