Earlier quoted context omitted.
If someone doesn't hit FU at $1M in the bank, you probably never will, which is ok. $1M is about 20 years of coast on a modest bay area mortgage + family healthcare.
And the remaining 30 years of life you have low ability to earn income, but face higher taxes and healthcare spend. To me, FU money is passive investments which yield a couple hundred thousand a year from businesses that can keep up with inflation.
It should be possible to live in the Bay Area on that, given that the place still has cashiers, cleaning personnel and maintenance workers. It won't be a middle-class lifestyle, but you'd have to make _some_ sacrifices in order to indefinitely work at whatever you want in the most expensive place in the world.
