Don't buy into that stuff about the USD @bozz. A lot of it is total bullshit.

The USD has 60% of its physical dollars outside the US. This means that it is global in its distribution. Also, there is $200 trillion worth of debt out there, much of it written in dollars. That means all payment streams are in USD. There is a lot of 30 year bonds out there (If I was at the Fed, I would start issuing out 50 and 100 year bonds).

One thing that people overlook about an overly financialized economy, which the US has, is that it protects the currency.
