Earlier quoted context omitted.
You are assuming that FAANG companies are offering "fair" compensation for the output of their engineers. How would anyone ever make a profit doing that? Employees are very rarely the exploiters and almost always the exploited.
If it wasn’t fair, why did you accept the offer? Let’s not pretend that FAANG employees are like an underclass that has to accept a job out of desperation.
Amazon does not get the richest CEO in the world by truly compensating employees what they are worth to the company. Facebook literally tells employees that they target 90-95% of "market rate" for engineering salaries, based on location of the office they work in, and they refuse to negotiate with competing offers, resulting in massive compensation disparities between London and Seattle/Menlo Park.
I'm 35 and compensated far and above what I ever could have dreamed of making as a teenager, but when I look at the tens of millions of dollars I've personally saved the company through my actions and work, I don't consider my compensation "fair". A pat on the back, an "exceeds" rating, and a 15% increase in my bonus for that half is peanuts by comparison.
