If it does what now? Fearmongering that intentionally whips up nativist xenophobia might do that. I'm not seeing how work visas in themselves would do it.
> Second, even when they do have US degrees enriches institutions and people that at best about half the country approves of and approximately nobody not getting paid by them approves of the economic model of.
I honestly don't know which institutions and people you're talking about. I can think of several fundamentally different candidates.
> This nation is in the shit is is because of you and people like you who adopt or condone policy positions based on something other than principals.
You're being self-contradictory. Either you have principles to which you hold regardless of whether "this nation is in the shit", or your only "principle" is "do whatever works to keep you out of The Shit(TM)". Which isn't really a very inspiring principle. Anyway, as soon as you start doing things for instrumental reasons, you lose your deontologist card.
If your principle actually is "stay out of The Shit by any means necessary", then you have to prove that what you want to do actually works to keep you out of The Shit. Starting by defining what "The Shit" means to you. Maybe what works is building up industry.
What you've offered only works on exactly the same kind of "principles" as doing things "to build up US industry".
An actually principled approach to H1Bs might, for instance, be to convert them into permanent residencies or citizenships, because indentured servitude is ugly on principle. That'd also have the practical effect of making people less beholden to specific employers, thus reducing the negative effect on anybody they might be competing with, but that's not the principled part unless you can say what actual, specific principle it serves.
... and, by the way, for any actually reasonable definition, your nation (no longer mine) wasn't particularly "in the shit" until recently. Just normal fluctuations. It hasn't actually even really landed in "the shit" yet, although the people running Trump have succeeded in breaking its last hold on the the catwalk over the shit vat.
