I think people significantly underestimate the economic power of the United States. For quality of life, income, and opportunity, you'd almost certainly want to be in, say, Atlanta, Pittsburgh, Cincinnati, Kansas City, or St. Louis (none of which are on the list) than Lagos, Nairobi, Bogota, Bratislava, or Bucharest (all of which are on the list).

I know, I know. You think of those as nowhere places. But that's because, again, you're vastly underestimating the economic power of the United States and its cities.
