Post some links to companies hiring at similar compensation levels. Or, are you suggesting that every Meta employee is in a position to just like off of any random job they can find, or even no income at all while they go off "on their own"?
Sometimes you need to realize you need to choose between having the cake and eating it.
There is more to life than money. I've turned down FANG roles my entire career, especially Meta. There is lot of work out there.
