Yes that's all good but you forgot to mention a possibly bigger threat and that's the fact that very soon America won't be able to service its own debt. Where it stands at the moment is around 26 trillion dollars and it's blowing out at a rapid rate. "Fishtailing wildly you may say". The next Greece possibly! It would be okay if America had a +50 trillion dollar economy to service this debt but unfortunately they don't.
