American manufacturing is not coming back until we no longer have the highest corporate tax rates, highest regulations, and unfair trading practices by countries such as China & Japan and many others.
Cost of labor is not the overriding factor most think it is. Most mass produced goods do not require a lot of labor hours. We have open markets where foreigners can dump goods at will. Yet, there are numerous roadblocks and tariffs on our exports to certain countries. Like Trump says again and again, they are laughing at us!
I think that is overblown. GE and others are paying no tax, but exporting jobs, IBM has no unions but still outsourced. Apple makes the Ipad in China. Few corporation pay the tax rate because of loopholes. Plus we probably don't want the water and air pollution, child labor of 3rd world countries.
It's all about making the most money for Wall Street stock approval and year end bonus getting.
