Some colleges encourage something similar. The Acton MBA program encourages alumni to sponsor new students so that their education is free (and based entirely on their ability to be accepted into the program). Once these students graduate, they are encouraged to turn around and to the same thing for the students behind them (out of a percentage of their earnings over the following years, until it is repaid).
It's not exactly the same model, but it does represent a take money now and payback out of future earnings template.The thing is A: repayment is encouraged, but not required, and B: the amount taken out of your future earnings is fixed and will end once paid.
That sounds a bit different. There's no real risk. The exchange is voluntary, after-the-fact, and if you make $10B the school doesn't (necessarily) get a percentage. That's basically a loan: you get school paid for now, and you pay it back over the next several years.
One or two fraternities, I'd heard, actually have you sign over some small percentage of your salary (1-2%?) for life. That's equity.
