I think it's important to note that this is very location-dependent.

In Utah, where this survey was taken, I'd be willing to bet the number of people with developer-like titles consistently bringing home > $250k take-home probably is less than 0.1% of the dev population, whereas in a place like SF/Seattle/NYC, it is a lot more common.

It's definitely location-dependent. My experience is primarily Bay Area/NYC/Seattle, and salaries will likely be lower outside those hubs. However for very skilled or in-demand specialists, it's definitely possible to get SF salaries while working remote in a cheap CoL area.
