Well, duh! Jobs are exported because the Federal Reserve's creation of money and credit out of thin air removes all real limits on what we can buy from outside our borders as long as we can convince other nations that our money will be worth something in the future.
In other words, we don't have to sell to China to get Chinese money so we can buy from China. As long as we can buy foreign goods without any foreign currency reserve constraints, we can buy from the lowest cost provider whenever we wish. This puts American workers into competition with Chinese peasants. Bingo! Their jobs disappear.
Hail to the Federal Reserve! The most efficient job killer known to the history of the world.
