Economic collapse is extreme. The US has "spread" its debt over the world while making the US the reserve currency. They have 17 trillion in debt and need 500 million years to pay that off! Problem is Obama (not his fault) borrowed more than all..YES ALL presidents before him just to keep things going its snowballing rapidly. Currencies collapse all the time..did the world end? Infact no currency has had global dominance for more than 100 years since the fall of the roman empire. The US will take the the world down with it...but its just a setback its not the end try not to stress
