Private financial institutions would no longer loan nearly as much money to students to pay for college, so less money would go through the chain of (student after graduation)->lender->(student when they were in school)->school. This means that overall, less money would be moving from students/graduates to schools.
Schools would have to find a way to manage with smaller budgets or get more government support.
