People who graduate from university have on average better health, better life expectancy, and better earnings than those who don’t.

Lorraine Dearden, Professor of Economics and Social Statistics in the Social Research Institute at University College London talks about how student loans are handled in a number of countries and why, just like free lunches, there’s no such thing as free tuition.
