They don’t make less. I know this because I work with them. We have laws that make that perfectly clear as far as h1b, and green cards in The IT industry and I expect laws are on the books for other industries that bring in folks from foreign countries.
And what, pray tell, would the prevailing wage be without a Biblically proportioned flood of cheap foreign labor on the market?
Or has the law of supply and demand been overturned by an act of congress?
I don’t know about where you are but, here in Silicon Valley there is a whole cottage industry of lawyers and consulting firms whose sole purpose is to “prove” that the prevailing wage for a job that paid an American $100K ten years ago is now only $65 or $70K to justify a low H-1B wage.
The kicker?
I’d cheerfully work for $65K, but can’t even get the interview, let alone a job offer.
