I'm glad that you escaped before the economic system got as messed up as it currently is, but there's a lot wrong with your point of view on this.
Those of us who live here do not exist as islands. We all participate in a rich economic web that requires exchanging services with lots of people. Teachers, bus drivers, delivery people, shop keepers, mechanics, plumbers, police officers... it takes a lot of people to run a society.
Typically the "not everybody has to be able to afford to live here" mindset has worked only when there is a wealthy exclusive enclave that tries to keep out poorer people and races they don't like, but when that community can still draw workers from more affordable places nearby.
The Bay Area has taken that "these people we depend upon for our lifestyle don't deserve to live here" attitude and applied it a region so large that people can no longer commute in. It leads to extremely dysfunctional societies.
