Right now we are in a period of flux and I am willing to bet that 20 years down the lines. You will have USA based automated manufacturers that do just this. Right now, due to misalignment of interests manufacturing has shifted to other countries, but the world can't be a sweat shop too long. So, the reverse trend will start kicking in sooner or later to equilibrium.

Moreover, unilateral hegemony is something that no country will be able to maintain in this system. Earlier the British were "outsourcing" their work to the colonies and getting raw materials from them at substantially cheaper costs. Today, we have moved beyond that and instead you have entities existing in different pieces of land to get the optimal yield.

So, in this interconnected world those realities are harder to maintain. What lies ahead is anyones guess, but something fascinating is happening around us and we are witnessing the start of a huge shift that no one can predict right now. The times they are a-changin'.
