> The calculus is pretty complicated. Economies of scale become a factor - is one large global factory more efficient than separate regional facilities?

It's not about efficiency. Companies in the US only build and ship their products from the opposite side of the planet because over there they can abuse the local slave labor and pollute the environment in ways that would never be accepted in the US. Even when they could easily afford to by accepting less profit, they aren't going to move production to the US when it means they can't take advantage of those things.
