Somewhat of a tangent, but I moved to Boston 3 years ago and have come to realize how punitive tax policy is towards high cost of living cities. $100k in Boston gets you the same quality of living as maybe $40k in Des Moines (my estimate), but the $100k earner in Boston pays more than 2.5x the tax of the $40k earner in Des Moines. Besides the cost of housing, I think this is the second most important factor in cost of living analysis, but I don't think most calculators figure it in.
