That's hardly the most important thing about developer compensation. The value a worker provides is a ceiling on their compensation, not a floor. As long as the "large internet companies" are receiving applications from more than one developer, they are unlikely to be paying $240K / year for developers who produce $240K / year of benefits. If the same people can handle building that feature for 2 million users and for 6 million users, the developers who get hired to build it for 6 million users will make 1x as much as the ones who build for 2 million users, not 3x.

How much impact does a laborer repairing a Dutch dike have? How much of that impact do they earn?
