90k to 900k is the difference between living as lower class to upper middle class at Silicon Valley.

Upper middle class? Is multi-millionaire not "rich" anymore?

[nowherebeen]

High cost of living city. A million doesn’t go as far as it used to (inflation). Think about how much real estate has increased in the last 10 years. That’s the biggest expense for anyone.

Silicon Valley is expensive, but not so expensive that $900k/year is only middle class. That's $40k/month or so after taxes.
