Even without novel approaches students already get non-subsidized lines of credit so I don’t think it’s unheard of

On another note the idea rubs me as immoral in ways that loans don't for reasons I am not quite able to articulate. Like viscerally seeming too far too similar to indenteture.
I found a link but couldn't add it to my original comment. There is a 5% salary payment for 15 years once the student reaches $25k. Sandbagging is possible but it seems like students would start working against their own monetary self-interest pretty early (from a salary perspective at least; who knows, I'm sure there's other creative ways to game the system).
So if you have a huge loan but a small income, it's more like a 30-year graduate tax than a loan you expect to fully repay.
In the situation above, it acts more like an investment rather than a loan. (i.e., there's no upper bound on the payment, outside of the 5%/15 year cap, so the student may pay back more than they receive)

Sort of like those radio ads that say they'll help you "not pay the greedy credit card companies that trapped you".
That's entirely the point. Tuition would have to come down so it's actually affordable, or there would be less people attending. Businesses might actually foot the bill for tuition to train their people, because there would be a shortage of qualified applicants.
There is no free market here.
