Take a look at the Harvard Law School loan forgiveness program. Although it does rely on 3rd party loans (in this case the third party is overwhelmingly the government), and so is a bit of the inverse of what you are proposing, it helps pay a quite generous portion of those loans under a broad variety of circumstances while not providing any repayment assistance to those who secure the most lucrative types of private sector jobs.
It is a sort of post hoc means testing, in contrast to the more usual undergraduate system of pre hoc means testing.
The federal government also has income based loan forgiveness programs (the current one is called Pay as You Earn), but it is far less generous.
Ah! Hadn't heard about this. Professional programs usually don't offer need-based aid a lot, so this probably still doesn't go a long way. I was thinking more for undergrad programs, where need-based aid is much more common, and not too many students (none for internationals) qualify for gov grants, which might have similar provisions.
