Since I’m clearly obsessed with this topic now and avoiding working on what I should be working on (sorry Will!) here’s an assignment for a smart economist out there. Compare the median wage for legal and illegal immigrants working in the same jobs in the same regions. (I’ll check JSTOR, maybe it’s been done) I would imagine illegal immigrants make less because they have less bargaining power. If that’s the case then one obvious solution for raising wages at the bottom would be to make illegal immigrants into legal immigrants.
