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.
