The US's days as an exporting superpower are long gone, and are not coming back. Exports are still high in absolute terms, but not at all as a % of GDP. High value items like cars and machine tools will not make up for the near total loss of other industries.

It's hard to believe that US workers could compete with foreigners that make 5-10 times less than they do, no matter how far the dollar falls.

China only needs us to the extent that they rely upon us to purchase all the items they make and we consume. That alone is not enough leverage to imply that China really needs us. We are nothing more than the junkie relative who always comes around for a handout and we all know the day of intervention is coming closer and closer with each blink of the eye.

What China will do if anything is gain an upper hand on the power wheel of America via ownership within our borders. We are the ones at the mercy of our wealthy neighbor. A lost super power in freefall.
