Generally around $150K in the N Virginia area where that is significantly more than in SF. When I was in SF it was around $200K. We're talking straight developers here, either right out of undergrad or a couple years out for stuff that isn't rocket science by any means. If that is piss-poor pay for a software developer, and it may well be, then it indicates a scarcity given average pay in other professions. Even if it's a reasonable salary, it indicates a scarcity. If there isn't a scarcity, then there would be plenty of out of work software developers just like there are plenty of out of work people in most other professions, but in fact there aren't. How much do you make, since you're asking for numbers? And how does that compare to PhDs in other fields where there aren't scarcities?
Again as a PhD I'm surprised that you're committing the logical fallacy of "I work in a big tech company and HR delivers me 2 interviewees a week, therefore there's no shortage of U.S. based software developers and any such claim is "just the usual garbage of corps not wanting to shell out for domestic talent."
