As long as all (most of) the vital components in electronics are made in Asia I don’t think setting up a factory anywhere else would make much sense. As pointed out by others, it’s not just about cost of labour and worker’s rights (also a cost in the end). If it’s just to be able to put “Made in the USA” on it, remember that although this might be a selling point in parts of USA, the rest of world probably couldn’t care less. (I might have read you wrong here, but I didn’t get the feeling it was about creating jobs in the US)
