Maybe I'm just too much of an economist, but I think tuition should be scaled inversely to GPA in upper year classes as a rule after adjusting for income (which is effectively just an argument for extensive merit scholarships). There's a strong public policy argument for having a well-educated citizenry, granted, but the achievement of that aim shouldn't come at the expense of maintaining high standards for grad school bound candidates.

What is to give light must endure burning.
