You actually think the rest of the world is going to walk away from a $17Triilion dollar economy.? stupid. The US market is the gold standard.
This $17T economy is also $18T in debt -- and that's just Federal government debt. We are the "gold standard" for global markets because we'll burden ourselves for generations to come with massive piles of debt -- just to keep ourselves deluded about maintaining our high standard of living.
The U.S. is not a "growth market" at all. How many more cell phones can anyone expect to sell here, for example, if we already give them out to our welfare cases?
