"From the student's standpoint, ISAs assure a manageable payback amount, never more than the agreed portion of their incomes…Best of all, they shift the risk of career shortcomings from student to investor: If the graduate earns less than expected, it is the investors who are disappointed; if the student decides to go off to find himself in Nepal instead of working, the loss is entirely on the funding providers, who will presumably price that risk accordingly when offering their terms. This is true "debt-free" college."
