A peculiarity of "median" is neither my income nor lifestyle are median. I'm currently thousands of miles from SV and earn and live at the 90th to 95th percentile depending on who's fuzzy math and crazy definitions you trust. So its interesting to know median expenses for something like coffee or restaurant food, but I'd never live in a median real estate so whats the standard of living like at the 95th percentile assuming I'd get a raise? Its pretty good for me and my family where I live...

Median would be relevant if you were talking about moving to CA to sell car insurance to tech people.
