> You know that if the tech boom didn't show up none of that would have happened.
The tech boom has obviously not hurt the real estate market in the Bay Area, but it's a common misconception that the tech boom is the primary driver.
There is a substantial amount of money coming into the Bay Area real estate market from overseas and a significant amount (perhaps most) of the domestic home buyers are not newly-minted tech millionaires.
The truth of the matter is that a lot of the well-paid tech workers cannot afford to buy in the Bay Area. This has impacted the rental market more than it has the home market, but the rental trend is one seen nationally.
