Higher education and social mobility
The New York Times had a while ago a whole piece on Chetty, Saez and co-authors about the lack of capital mobility in the US. No surprises really. Turns out that universities can increase social mobility. The problem is that universities don't do enough. Bucknell actually has considerably more students from the 1% than from the bottom fifth. One way to increase social mobility would be to expand the scholarships for low income students. Somehow I doubt that the guy from Trump University would do much on that front.
