Because most of the shiny things in SF were paid for with equity. And there are plenty of shiny things in SF. I am not saying you should work for equity, but I think you should realize why the real estate is as expensive in SF as it is. There are plenty of times when people got screwed over, and there are also - fewer, but enough to move the market - people who didn't. So when you ask the question "how could you have been so incredibly stupid to believe that equity is not worth $0," you just have to look around yourself and ask "how come that zillow lists so many properties for over $10m?" You shouldn't count on your equity returning anything, but you also shouldn't listen to people who take an overly unhealthy view at the potential upside.
Even at FAANG, not enough people have the seniority for their base salary to turn them into buyers of $10m homes. I appreciate your point that RSUs are different from options, but I still think it's indicative that cash rarely comprises the majority of the wealthy people's income.
Oh, fully agreed that cash rarely comprises the majority of wealthy people's income - but my point is that most of the tech wealthy in the SFBA comes from FAANG equity wealth, not startup equity wealth.
Startups exits sometimes make a handful of people mega-rich, but as this thread has revealed, making ordinary employees rich is quite rare. Not so rare are the people who hang out at FAANGs, collecting large amounts of equity, and riding the industry up. And yeah, the wealth in this case is typically not of the level to buy $10M homes, but $2M homes?
Once in a while you have a founder who strikes it rich, but that effect is overwhelmed by the more numerous folks just riding $GOOG, $AAPL, $FB, etc. to multi/deci-millionaire status.
Sorry, I wasn't suggesting anyone was stupid for believing the hype that founders use to punt their stocks. What I was trying to get at was whether you had an idea of the valuation of the stock relative to your exercise price. If so, and that looked good, what happened to your company for it to sell at a low price?
