As far as $200K being high adjusted for COLA, in the burbs where I live. $330K gets you a house - brand new build in a top rated school system with five bedrooms, 3.5 baths, 3000 square feet with a yard, two car garage, and a separate nice size office. What does that get you in SV?
Anyone making at least $110K can buy that house with an FHA loan with 3.5% down.
What a company is going to pay is based on the supply and demand.
Part of a free market is realizing that, if others are earning more money for the same work, there is a good chance that you are undercharging your employer for your services.
Most companies I've known charge what they would consider "base rate" + some kind of Cost of Living multiplier. See Buffer's example: https://buffer.com/salary/staff-engineer-web/average
