And unlike 2008, many of these companies are more mature and much more exposed to the broader economy. Cloud computing, Ads, GSuite, etc... There are a handful tech companies that will probably thrive (Netflix, Zoom, etc...), but most of them are probably going to see big drops in revenue.
And considering that most of these companies have plenty of fat to trim (how many Alphabet moonshots are bringing in meaningful revenue, let alone profits?), I don't see how declining revenues won't result in some belt tightening. And when that starts happening, how many of the top 30% are going to be buying $2M-3M homes. The mortgages on those things are like ~$15k a month, and CA unemployment maxes out at ~$2k.
It is certainly possible that Bay area real estate weathers the storm just fine. But I really don't see a compelling case for it. Salaries can, and likely will go down. And bay area real estate is at all-time highs relative to incomes.
You have no way of knowing what the price might be when you are able to exercise your options. You also don't have to exercise them, it's your choice. Equity compensation is always a gamble.
If that’s true, well, I guess I am not in the top 30% of employees of big tech firms.
