That’s not the same as an income share agreement, as the school gets all the money regardless.

it’s not the same thing but the point is your repayment schedule is dependent on your income in both situations.

That’s not the main value of an income share agreement. As you’ve already pointed out, simply creating a payment schedule has already been possible.

the main benefit is just that you don’t owe anything if you can’t find a job?

well the ones suing are the ones who couldn’t find a job and not happy about it. simply not having to pay up is not much of a consolation.
