Considering the vast swathes of 1.5M homes across the Bay Area that were <$100k in the mid-70s, you didn't need to be anywhere near a millionaire to making a killing in real estate if you've been here 50 years.
That's very true in dollar terms, but wealth is owning 4 homes, or a couple apartment blocks, or being able to retire at 40, right? That's what most people are seeking. And if folks were able to achieve that in the 80s from being extremely-impactful ICs at big companies, maybe big companies were paying select employees more than the general public was aware?
