Here's my counter: what if, instead of taxing students after their graduation, we taxed all adults income, then used the tax proceeds to make university tuition cost-free. The advantage would be that more students would attend, we'd have a more educated society, and alumni would not be worried about having to take the best paying job instead of one that they desire. It's win-win-win, taxpayers get free access to universities for themselves and their children, students avoid debt or garnished wages in the future, and universities get government support and can shut down complicated administrative overhead for helping students navigate financing. Now I know your thinking - does it scale? Yes! We have data from secondary and primary schools with the same cohort of students, who attend school for no cost. Attendance and graduation of these schools is closely correlated with life outcomes and success! We could apply this existing financing model to universities and solve the problem of tuition fees with by reusing the ideas from other tuition-free primary and secondary schools. Prob a bit long for an elevator pitch, but hey.
