How much of that is reality or how much is is suppresses wages will always be hard to pin down.
A basic starting point would be cracking down on H1B mills that explicitly do wage suppression + more scrutiny on big companies like Amazon using it. There's some big H1B consultancies designed to undercut gov contract tending who are much more blatant despite hard rules in H1B meant to stop it. Biden admin passed some new policies to help combat it but enforcement has always been problem #1, not a lack of rules meant to protect American workers.
Many things could be going on. You should propose a concrete explanation instead of some vague "something is going on" placeholder which could uncharitably be described as dog-whistling.
For example, consider that leaving one's country is difficult and, so, the distribution is skewed towards individuals with higher skill and talent.
I'm not saying that is the only effect at play here. My point is there are many effects and a lazy "something is going on" statement does nothing to understand that complexity.
Not sure where you got that from. I am clearly calling for a concrete explanation.
> I'm not sure yours fully accounts for what's happening there.
Yes, my explanation is also bad because this is a multidimensional problem and I was only pointing out one possible effect.
Whose to say an American, given the same opportunities, couldn't do this as well? If you look at where the top AI companies are, only 1 is in China.
I don't think h1b mills impact tech workers as much. Most of those cases seem to be in the healthcare space or in low end tech jobs that Americans probably don't want anyways...
