One thing to consider: how much of that salary is going to the high cost of living in the Bay Area? The numbers are definitely higher but I wouldn’t be surprised to learn that the percentages of people who are n months away from needing to find another place to live – especially if that shock turns out to be sharper than it is short.
I lived in San Diego in the mid-90s. One thing I remembered was that the very first job I had doing QA for a COBOL vendor at $15/hour had not just one but multiple applicants with doctorate degrees apply. That was fallout from the Cold War: they’d all worked for big defense contractors on projects which were scaled back, suddenly going from comfortably above average income to nothing. One of the things a bunch of people found out abruptly was how bad it can be to have a lot of your net worth tied up in housing: the market slowed dramatically (nobody needed houses near those employers, many people were waiting to see how the market went, etc.) for everyone at the same time, so a house you could easily have sold before would be on the market for a year.
Things are better now in some key ways (remote work, portable skills, etc.) but I still would be surprised if a bunch of people aren’t getting a rough reminder about how badly correlated failures can suck, especially for the ones not making experienced software engineer salaries.
