When China Will Be Able To Pwn The US: "When China has a large internal market which has reached takeoff, it can sell mostly to itself, and will no longer need the US as much. Neither will any other country, since they can sell to China, with a much larger market. Sure, everyone'll be happy to sell to the US, but they won't need to. At that point, when the US has a financial crisis (and it will, unless things are cleaned up) China doesn't have to keep buying up treasuries or see its own economy crash out. It can say 'no thanks'. It can even start offloading all the crap securities it has. If it, or other countries do so, the US dollar crashes the floor."
