"Market" is weird to measure, because you're not really asking what market rate is, you're asking what your baseline is. If you can get a FANG job, the number you care about is effectively the average of what FANG would pay. If you can't, then it's effectively average rate outside of FANG.
AND, arguably, "market rate" in SV is below market rate elsewhere, especially when you factor in cost of living.
So anyone who is good enough to work for a big company you have no interest in?
