If so, I agree. It's this idea of nationwide economic efficiency being the be-all and end-all goal of social policy, which completely ignores the actual "social" aspect of gutting small towns even more than already happens, not to mention instituting systems of effective apartheid that attempt to exclude people from important economic hubs.
Edit: ironically, Princeton itself is a pretty small town - 17,487 people in Princeton proper. Of course it's probably not what the study had in mind, and it's about 1.5 hours from NYC and an hour from Philadelphia, making it part of the Northeast megalopolis. Still, "small town" may not be the right term for what they're getting at.
