I don't know where you work, but as someone who has been in the industry 20 years - keep in mind - stocks don't always go up, and stocks can go to 0. I agree in general that getting more shares is better than getting less, but it's not a guaranteed win.
That's a good comment. The best case scenario for tech employees is that this is just a temporary correction, and the bull market will resume after this short break.
This seems to be the implicit assumption in GP, for example.
However, there's no certainty that will be the case. The next few years could be a sustained bear market, in which stock prices appreciate very modestly.
And while I wouldn't worry about stocks "going to 0" at a big corporation like Amazon, it's certainly possible for the smaller tech companies.
While it's generally a good rule of thumb for stocks, we're specifically talking about FAANG stocks here. None of those are going to zero ANY time soon.
If they go to 0, we probably have an immediate global crisis on our hands. We're not talking about hyped startups here, we're talking about mature, global organizations that have fueled society's growth for the past 2 decades.
