What do you mean? California has an 11% top marginal income tax bracket - most of my income was in that bracket when I worked there. Add to that fairly high local sales taxes, and property taxes for the new (high income) residents as well as the commercial properties where they work.
Rich people only pay long term capital gains. Bezos salary is like $79k. Others have income of $1.
We're talking about state taxation. I don't know how California works, but New Jersey has no concept of "capital gains". It's all income.
I assure you Bezos pays sales tax and property tax on all the buildings he owns. The state of Washington doesn't even have an income tax.
