Is this just posturing (I won't speculate on the intended audience), or does the admin believe this will actually net more jobs for US citizens? TFA doesn't go into great detail about how this actually pushes offshoring - the variety that I'm familiar with at least (X/Y% blend of US/"near-shore" aka anywhere-but-west-asia roles). I have no doubt however that Y is just going to get larger while X stays the same or decreases (not even factoring aipocalypse). What constraint specifically makes them believe this is going to net in the way they want us to believe?
