One interesting finding was that not only SF salaries are much higher compared to rest of the US, but users from SF tend to over-estimate how much the rest of the country is making. You can see this effect in the third map at https://salaryfairy.com/blog/first-10k-users-salary-maps-and...
For what it's worth, I work for a company that has offices in both Atlanta (which is probably a relatively low-wage market) and San Francisco. I was given a choice between the two offices (I lived in SF at the time of the offer but was looking to move) and was offered X in Atlanta or about 1.2X in SF.
(I took Atlanta, by the way. The cost of living difference is much larger than 20%.)
