> Doesn't change the fact that H1-Bers have turned the US IT job market harmfully hyper-competitive for US citizens
Sure, maybe. I don't know. I don't think that explains why "since the widespread adoption of generative AI, early-career workers (ages 22-25) in the most AI-exposed occupations have experienced a 13 percent relative decline in employment even after controlling for firm-level shocks. In contrast, employment for workers in less exposed fields and more experienced workers in the same occupations has remained stable or continued to grow" [1].
Unless the ratio of H1Bs in these fields to recent-college graduates has exploded in the last 5 years, immigration is not a sufficient explanation for the effect.
