And my point is that an “everything else being equal” argument about the income and spending of an individual is not particularly useful when discussing demographic issues.
Yes, the cost of things is more expensive in dense cities, but by 2x-3x for some services and not at all for buying a pair of jeans from a retailer - those prices are pretty much uniform everywhere, modulo state/local taxes. I'll argue that one's quality of life is better in SV on $250k vs $70k in the rural midwest or $100k in a midwestern city - obviously this will depend on spending patterns, which depends on personal preferences. But for me, it's a conscious decision to make more and spend more on a west coast city.
