Dartmouth worthy David Goodman has an op-ed in the NY Times called Too Many Doctors in the House. It makes the arguments that you all know well, but it does contain this lovely zinger.
The association of medical colleges has argued that increasing the doctor supply overall can remedy regional shortages. But in the past 20 years, as the number of doctors per capita grew by more than 50 percent, according to our measurements, most of the new ones settled in areas where the supply was already above average — places like Florida or New York — rather than in regions that lack doctors, like the rural South. Medical training is an expensive business, and it makes little sense to waste additional public dollars to perpetuate doctors’ preference to live in affluent places. (my emph added)
