Ultimately your business’s total revenue is a function of external demand for what you sell. Within that limit, some employees have a big impact on realizing that revenue, some have a small impact. What they are really worth to you is their share of contribution of revenue by that impact.
What I have said is that virtually all companies employing software engineers experience this impact from software engineering in similar ways (meaning the engineers’ value is much closer to their direct impact on revenue than some lower “market rate” wage floor).
It’s frustrating that you are misinterpreting this as me saying other companies earn the same profits, in absolute dollar terms, as tech companies. Because I never said that at all - and more importantly, that does not need to be true for my earlier statements to be correct.
A company doesn’t have to make the same profit as FAANG to justify that the fair value of one of their software engineers according to their revenue contributions within the company’s (much lower than FAANG) profits is already at a FAANG salary level (which they already have the ability to pay).
Remote work just takes away the greedy rent seeking mechanism (local “cost of living wage” excuses) that had been used to artificially suppress what should have been a FAANG-level wage (paid out of the current revenue) all along, based on the way the company leverages software engineers for their contribution to existing, current profits - not any hypothetical ability to generate future FAANG level revenue per employee.
