In a sense, it still comes down to supply and demand — if applicants, upon graduating, all requested to be reimbursed for, say, 25% of their tuition up front and to the university they graduated from, we'd end up with reduced salaries compared to just distributing those 25% to the new employee over a number a years.

But how do you get all students to agree with this in principle when someone is in more rush to start earning an income than others?

However, employers would then look to only hire from universities that do good teaching, so maybe it's a win-win?
