Worth noting that this looks like total comp. Which is fine, but the implication of course is that a good percentage of the comp comes from stock, which is a bit easier to manage as a form of payment than actual dollars.
What I mean to say is that I don't think the actual stock performance affects these numbers
If you can hire into a FAAMNG during a stock market crash, you're set for life.
The shares are worth less in 4 years , etc.
Sometimes, you'll hear this described as "golden handcuffs". You get more money, but it is money that disappears if you ever leave the company, providing an incentive to stay. This is, fundamentally, a wrong way to view the stock grants. Instead, they should be seen as a temporary raise of X/Y dollars per year, that expires after Y years. The money isn't yours until the stocks vest, and until that point is nothing more than a commitment to give you stock at a later point.
