I think the simpler form of that question is "what's wrong with globalism?", to which there's many answers.
One of the foremost would be that an American company should support the livelihoods of the American people, especially as long as other countries like China wouldn't allow an American to work so easily in the reverse situation. It's just a natural tribal instinct, also, to care more for the welfare of your neighbor than someone across the world.
I'm not commenting on the validity of those arguments, though, as I think a core part of America's success is being unusually open to immigration.
