Not including stock. Just thinking back to last time I solicited job offers I live in a US metro area with a cost of living about 1/3rd less than SF according to Wolfram Alpha's data and got offers that ranged between 120k and 220k. Anecdotally most of the senior level engineers I know in my area are making between 150 and 200k. Adjusted for cost of living an employer in SF would need to pay something like 200 - 300k to just match their current salaries. Maybe the stock portion of a salary would make up for that difference but I don't see how they are competitive in the wider market if they are paying 150k for senior engineers.
