This reminds me of something I remember from college but cannot ever seem to find: "The Jevon's diagram" by which I mean a two country system, with country containing two groups: highly educated and not very educated. The two countries have very different proportions of each group, and the analysis is around free immigration vs no immigration, and shows the harm done to the larger number of less uneducated in one of the countries. Anyway, I'm not going to do a good job of describing this thing, from 20 years ago in class, here, but if anybody knows offhand what I mean and can point me at an article or source on this, I'd be very appreciative! It's bugging me from way back! (where are my notes! Silly tobmlt, not taking notes in latex back then)
