In this exchange with a student at Florida State, Vice President Joe Biden conceded that federal student aid has contributed to the rise of tuition, but argues that if it weren’t for such subsidies, fewer students would have gone to college. No doubt about that. What Biden doesn’t understand or won’t admit is that many of those who have gone to college learned little and have jobs that they could have done without their degrees, and also that without the big federal push on college, we wouldn’t have the widespread credential inflation that we do.
