There's between 5 and 16 million tech workers in the US depending whose definition you use. The tech sector unemployment rate is 2.8% per https://www.comptia.org/en-us/about-us/news/press-releases/t...

That is, at most, less than half a million people in the field and the majority of those jobs aren't the ones looking for overseas hires anyway. If we take CompTIA's number of roughly 5M tech workers it's 140,000 people, not "literally millions."

If you have better numbers, please, let us know.
