You're thinking of "Income Share Agreements" which have made their way into the USA.

"ISAs provide students money to cover college costs, and in exchange, students agree to pay back a percentage of their future income for a set period of time—interest-free and capped. At Purdue, for example, a senior majoring in economics who took out $13,000 in a “Back a Boiler” ISA would pay 4.39 percent of her income over 100 months, up to a maximum of $32,500."

"If a student struggles to secure a job after graduation or earns less than $20,000 per year, the college would collect no money. If a student is extraordinarily successful financially, Purdue could be paid back up to 250 percent of the amount originally awarded."

That sounds good, thanks. Although it seems like the terms are fixed, and it's only smallish amounts for already-attending students, but still a great start.

I imagine there are a lot of university foundations watching the Purdue experiment while planning their own version of ISAs. Taking loan interest away from banks and injecting it back into university endowments has to be a very appealing idea.
