The problem with the notion of a global currency is demonstrated by a complete and utter inability to manage smaller currencies worldwide. What on earth makes anyone think these same people can possibly manage a "global" currency when they have demonstrated beyond a shadow of doubt that they cannot manage the Euro or the Dollar? The same is true for the so-called "one world government". These folks who claim to be "leaders" haven't demonstrated the ability to successfully run a small city, much less something as diverse as the entire world population.
