Supply chains run in and out of every country and a simple products, say a pharmaceutical, can be composed of materials from lots of different places, which can be changed in a heart beat. The problem for us in the USA is that we need to employ as many people as possible but can't compete for the cost of labor for major manufacturing around the world. More than anything this is what causes the huge wealth gap. The answer for me is to do as much as possible to foster small businesses rather than large ones, because the former provide the majority of jobs. This would mean lowering taxes and decreasing regulations that impact small businesses.Unfortunately, our politicians care only about their own power and not making the best policy decisions for the general well being.
