This article was a bit scattered over the various sources of issues (high living costs, low labor pool (leading to high salaries and high turnover), reduced high-skilled chefs, high taxation, complaints about customer base with some nativism thrown in); figured I'd try simplifying it. On the labor side, there's enough labor competition to drive salaries of line cooks to $50k/year. That's about $38k post-tax, which even after spending spending $19k/year in rent (split a two bedroom maybe 40 min from downtown) leaves $19k. Not great, but mind you the average line cook in the US is pulling $30k/year pre-tax (24k post-tax) -- the COL difference is pretty much compensated for. Where things break down badly is with older, more experienced workers that have/might have families (e.g. the cook with 4 kids in the intro paragraph). Space comes at a premium in the Bay Area and if they prefer to not be crammed in to a small place, the salary an experienced worker can make isn't going to cut it to cover the desired marginal living space. The final piece in the puzzle is that the desired salary multiple of these experienced workers (over entry-level ones) is higher than their productivity gains. That is, if the experienced cook needs twice as much take-home ($110k pre-tax) as the entry-level one (due to family needs), unfortunately, there is insufficient customer demand to pay 2.2x as much for food for this higher quality. (but mind you much more base demand in SF than elsewhere!). Result is that experienced folks move to areas where housing costs (per-sq feet) are lower as a percent of salary. Net effect might be that the dominant strategy for someone in the restaurant business is to start out in SF but later move to a somewhat lower COL area. With such a strong economic incentive, restaurant composition will likewise follow; city policies, etc. are likely secondary.
