Yes, but that ship sailed. Bernie Sanders used to be for the American worker. He used to block re-settling refugees in his state. Nowadays even he doesn't care to curb immigration or off-shoring. Some people in the Trump admin make motions about curbing some (unnecessary legal) immigration (ala Canada and Australia -vetting for skills needed). Very few want to curb offshoring. Both Democrats and Republicans monetarily benefit from offshoring and increasing competition for American workers. Elon pretends his companies could not run without more imported workers --sure, I get it, you don't want to bother to train a capable local population, much of which is descended from relatively recent immigrants.
