It's not possible to predict that at this point. Trump has been extremely vague on how this would be implemented in practice. He won't even be in in office for another two months. We don't even know if he'll actually implement it. For all we know, it could have just been a populist attention grabber for the election.
When he is actually sworn in and/or starts making concrete statements and/or policies regarding this, it will be possible to answer this more objectively. At this point, we can do nothing but speculate.
