College will never be free. It will always be expensive. The question we need to ask is: who should pay for it, and when? The current model — used throughout higher ed — forces students to pay a lot at the poorest point in their lives, burdening them with debt for decades. But a bold new way called "Hope Forward" flips the current model on its head, providing a tuition-free education for students up front. Graduates then give back voluntarily in their earning years out a spirit of gratitude.
