You want to allow U.S. companies and Americans to import an unlimited number of immigrant workers also to provide their cheap services they offer? how would you like 2 billion immigrants to come to the U.s.A if we remove all immigration restrictions as you want to remove all trade restrictions ( allowing China to dump unlimited number of products they stole the tech from us to produce).
If the stated policy aim is to save jobs and increase domestic manufacturing, then cut taxes across the board. Don't expect some government bureaucrat to choose which of your taxes he needs to raise, and which industry he wants to favor over another. Which is all tariffs do . . . even protectionists admit to as much.
