Yes a lot of people are content with their earnings from 2 years at a FAANG. They aren't thinkings its enough to live off of forever, but its enough for:

A house somewhere else and never paying rent again

or

A downpayment on a home in a high priced area where demand doesn't seem to stop, which is always a low-interest leveraged investment that has cashflow opportunities

or

"Taking a break" which means years of luxury at every music festival and socialite event while optionally networking and pursuing other fulfilling money-making activities, with almost no opportunity cost of having 'gaps' on your resume

or

Riding off the resume entry of being an "ex-Googler" to secure advisory roles, raise capital easier, get C-level titles at someone else's startup

or

Joining another FAANG company at a higher premium

and/or

Leaving the company so you can write covered calls on all those shares you earned, for passive income

if you're compensated 300-400k annually, you'll have enough to move somewhere else or take risks if you play your cards right (huge savings, etc).

Or the other options is to jump to a different companies that offer more money or more equities or higher level.
