Tell that to all the people in the restaurant and service industry out of a job in Downtown San Francisco.

That's the effect of thousands of tech workers leaving. In terms of relative wealth, tech workers have more in common with restaurant and service workers than they do with billionaires: https://mkorostoff.github.io/1-pixel-wealth/

The presence or absence of a billionaire in a given jurisdiction won't be the deciding factor for those industries as evidenced by every other city without tech billionaires that has a thriving restaurant and service industry.

You’re so close.

Do you remember when SF passed a dumb tax law and Stripe had to move their office out of town? Then all the office workers had to go too (or go remote), then the completely obvious effect described above happened?

I remember. My friends in the restaurant industry remember.

Condescension doesn't make your argument more compelling. Your "friends in the restaurant industry" would be better served by curbing income inequality rather than kowtowing to billionaires.
