Where do you live now, and how aware are you of the difference in the cost of living (really it is the cost of housing that drives the discussion) in different markets around the country?
Where I live now in flyover country, I could make as an attending virtually the same income I could make in, say, Los Angeles; even if I could make slightly more in LA, the high marginal income tax rates would eat into it, as well as other higher costs in CA (gasoline, etc). The house I rent where I am in residency now, a single family home in a great neighborhood, etc., is worth maybe $250k; in Los Angeles, it would cost at least 3x, and maybe 4x as much or more. In the San Francisco Bay area, the same house could cost 10x as much...
