Vermont and Maine are the least urbanized states in the US, and close to the bottom of average GDP per hour worked.
Our friends at Vermont Tiger see these data as a problem, but I don't see what the problem is. These states are in control of their development, their industrialization, their welfare payments, etc. Apparently they do not seek growth or development. What's wrong with that? It's their choice, and apparently most people who live in those states like it that way. Money isn't everything: some seek it, some just want enough to survive until the Social Security gravy train kicks in, paid for by the labor of the folks in the wealthier states. Rural and rustic, with the good and bad (see the Rumford (Maine) Meteor) that come with that.
If those folks want more jobs and urban life, there is a simple solution: bathe, shave, get a haircut, and pile your stuff in a U-Haul and move to the resurgent Bronx in a few short hours. Job choice, no big snow problems, walk to the Stadium, lots of bars and bodegas, quick express subway to the Metropolitan Museum. How bad is that?
I like the idea of each state following its own heart. Each one is crazy and/or corrupt in its own way.
