Basically, they avoid Taxes, Tariffs, and the Laws of the U.S. (regarding unfair competition) by creating Subsidiaries, Corporations, Companies, and Operating Units, designed to maximize their profits through the use of the cheapest foreign labor to manufacture products that are then imported to the U.S. at costs that Domestic Manufactures cannot compete with because of the higher living standard and subsequent cost of Domestic Labor.
That fact has forced more and more U.S. Manufacturers to not only import from a third party importer, or directly from a foreign manufacturer, but to manufacture from their own plants now located on foreign soil.
Lower U.S. retail prices meant the U.S. worker didn't need as much money to purchase products and therefore they could have more...or they could be paid less and have the same.
This logic, THE GLOBAL ECONOMY, is defined as...Those who have a higher standard of living must sacrifice, and have less, so that those that have a lower standard of living may may prosper, and have more.
SO...the Multi National Corporations got richer, and the Foreign Governments got richer, and the Foreign Worker got richer...and the U.S. Government, and it's People got poorer.
TO BE CONTINUED, I'm tired.
