Sooner or later China will stop linking it's currency
to the U.S. dollar.  When that happens there will be  a huge
rise in inflation as Chinese goods cost more.  The factories
that were once in the U.S. to build these goods will be long
gone so there will be no one to produce the goods domesticly.  
China will get an immense windfall profit.  The U.S. will have no
real recourse since the goods are currently artificially cheap
and it will not be economicly feasible for the U.S. or another
supplier to replace them at that price.  
 
Economicly, China will have her way with us.
Assume the position!
