This is how it works. The more money people have the more business will charge you. Real state is the one getting the biggest part as you cannot get more land that the one that already is.
Now stop a moment and think about all that people that is NOT part of Tech. That people that has normal salaries but live, or used to live, in that area.
Social democracy, where the well-being of citizens is as important as the business needs is the way forward. Better public transportation allows people to live farther away but do not wast more time on commuting. Social housing helps the people that cannot afford to pay the rent but is needed to run services, local business, etc.
Citizens should be plan for the citizens not just for Big Tech or the next Big Whatever.
No way would we have been able to build anything nearly so complete if we'd had an SFBA cost-of-living clock ticking behind us.
