I do wonder about this. I struggle to believe that the average FAANG employee creates their salary in value. Companies are so flush with cash they are willing to bid up salaries across the board, but it seems like that is a management decision. You hear people openly speculating that Google could cut staffing by 50% with no impact to revenue, which seems about right to me.

Not sure about this. Many big tech companies are very productive an generate a lot of income.
