At least for now the US does have several income based repayment plans. The best one for most circumstances is PAYE (pay as you earn). It requires payments of 10% of disposable income, i.e. dollars earned after 150% of the poverty line, and the debt is discharged after 20 years of payments or 10 years while working for certain government or non-profit entities. This program is partly the result of regulatory rule making and so could be sharply curtailed should the President or his underlings wish to do so.
