Sorry, but do americans really hurt by H1-B/L-1? I never heard about lack of need for tech people anywhere in the world. Isn't world's universities produce like 3% of required amount of tech people needed?

If anything, any restrictions on H1B force jobs to move out of the country rather than resulting in more "American workers" getting hired. With COVID forced WFH transition with no loss of productivity - even medium-size companies without prior experience in offshore employers are now willing to consider remote tech staff (anecdotal), and will be happy to pay 25%. Unless a very protectionist tax regime accompanies this legislation hard to see this going any other way.
Full disclosure: I am on H1B, and am partial to the visa that helped me build my life and career in the US. Now its a real possibility that I, my ineligible to work spouse and my three "very much American" children will have to leave this country due to these attempts by law-makers to find a bogeyman to target their frustration against.
EDIT: I don't know why on earth I'm being downvoted. I'm speaking from first-hand experience as I have moved from one company to another on H1B and I know other people who did.
