Because in my experience, the “everyone who works at a FAANG is a multi-millionaire” meme is 100% bullshit. Especially when I read things like https://news.ycombinator.com/item?id=26336029
My other comment you linked I still stand by. But you don't need to be IC6/L6/E6, refreshers and equity appreciation are very powerful if you are lucky enough to get both.
That said, I’d definitely be interested to see actual statistics about own vs. rent for people in tech in the Bay.
That's without any kind of growth, investment, stock options growing in value, raises, etc.
