How cheap can it be made locally? When you consider that try and take in mind comparative advantage.

I understand that price doesn't take externalities into effect. That said price is the best way we have to allocate resources - it conveys that information better then any other tool we have. If price indicates to people that toothbrushes should be made in China and shipped to the U.S. then I tend to think that's probably the most efficient way to do it.
