I'm not sure where you're getting that from in my comment. I never said US citizens should want H1Bs for everyone with zero vetting, only that they are a net tax positive.

It's not a dichotomy of maintaining the status quo or getting rid of H1b completely. At least in big tech companies, they do follow labor market tests and prevailing wage tests and so on that are designed to vet that there is an unmet need and that visa holders aren't underpaid. I won't deny there are visa mills and consultancies that game the system and pretty much explicitly just hire cheap foreign labor, but this is a thread about H1B in the context of Amazon layoffs, not InfoSys layoffs.
