Except these programs weren't importing top talent, but the same talent the locals have, to suppress their wages.
Good luck telling people affected by mass layoffs and getting rejections that the country need to import more talent because there's a "talent shortage".
Top talent means Nobel laureates, distinguished fellows in niche research fields, etc , not more full-stack devs and Microsoft Certified IT specialists, that's not top talent, that's average working class jobs, and the former category already has a red-carpet express-way through the US immigration system called an O-1 visa or "Operation Paperclip" in case of emergency, but H1B workers and diploma-mill grads aren't that, they're corporate welfare in human form.
