I made no claims regarding the geographical distribution of physician wages. I specifically claimed that wait times for specialists in Boston is on the order of months, which I speculate is due to the medical board artificially limiting the number of physicians.
But then, revenue does not correlate with scarcity anymore?
To be clear, I think you're right up to a certain point, but it makes some sense to be very elitist about who can practice in what you'd like to be the medical 'pride of the nation'. Now, scarcity in other regions is another matter, where it makes sense to relax standards. How much you relax the standard is a matter of how low you accept to go in terms of quality.
