I don't think there's granular enough information in there to support your conclusion.
To illustrate, imagine that IT workers used to get paid a $100k real wage in 2000 and a $50k real wage today. Imagine computer scientists and programmers got paid a $100k real wage in 2000 and get a $150k real wage today. Bundling them all into IT would lead you to mistakenly conclude that a computer scientist would expect to make as much today as they did 10 years ago.
Can someone confirm this logic is correct?
I don't know what the real stats are, but you haven't provided them. I also notice that the Brookings article you linked states that real wages have increased for those occupations in the past few years, but I don't how if at all they are bundling professions differently.
"Or is the hidden truth quite simply that large supplies of guest workers allow many firms to swap out higher-paid, high-skill domestic workers for lower-paid, high-skill guest workers?"
The Brookings article you cited states the opposite. Foreign workers get paid more. If there truly are enough good programmers and computer scientists available in the states is there a conspiracy to subject oneself to the nightmarish visa system and pay high legal fees to be able to hire foreign workers and pay them more than Americans, all the while not offering high salaries to qualified Americans? What would motivate one to do that other than a shortage of qualified candidates?
To be fair, it's not my conclusion. I just suggested an alternate explanation. :)
You're right that the Brookings article suggests that my quote isn't the case. I wish we had more information on how they controlled for different effects. IIRC BLS etc don't generally control for cost-of-living, and Brookings doesn't discuss the issue except for in the conclusion:
Likewise, the bureau should also consider how demand and supply play out in regional or metropolitan area labor markets, since job search and recruitment often happen locally.
I'd be interested in seeing those results, as I would expect a greater concentration of H1B workers in large metropolitan areas (SF/SV, NYC, Boston), where wages are much higher than the flyover states (where I'd expect less racial/ethnic diversity).
Good point on the location of H1B hires. I wish we had more info too, it almost feels like nobody is genuinely trying to measure the right things and instead retro-fitting data to fit their conclusions :/
