the euro was only created in 1992 after fall of communism in europe. the reason it was created so the europe would not go to war like world war 2 reasoning if everybody had common financial interest there would be deter war. in event of war fiat currencies or new regime or marshall law states. become worthless. http://en.wikipedia.org/wiki/Euro funny thing is that zimbabwe doesn't have a currency,,everybody in zimbabwe uses the euro and US...totall weird...i mean the people in zimbabwe doesn't even have central bank. letting a foreing entity to determine countries fiscal policy or monetary policy like giving up on a countries soveriegnity..hence the riots in greece,ireland etc.
