 It's like, why would you ever do that? Because the housing cost is so much lower that I actually get a gain. When you go and read the work, they have even more interesting details like high-skilled workers can still get a gain by going to high-wage areas because for them the housing cost is a smaller share of the budget and the wage gain is larger. But for a janitor to go and move to New York City today from Mississippi is a way to get poorer, not richer.
