Ron Paul (in 2011)

The euro was built on an unstable foundation. Its creators attempted to establish a dollar–like currency for Europe, while forgetting that it took nearly two centuries for the dollar to devolve from a defined unit of silver to a completely unbacked fiat currency note. The euro had no such history and from the outset was a purely fiat system, thus it is not surprising to followers of Austrian economics that it barely survived a decade and is now completely collapsing. Europe’s economic depression is the result of the euro’s very structure, a fiat money system that allowed member governments to spend themselves into oblivion and expect that someone else would pick up the tab.
