I think a history lesson is in order. As it stands most would agree that the U.S. dollar is the closest thing to a recognized world currency but surely you realize this did not happen overnight. In the late 1700's the United States began minting silver and gold coins (at the time no one could imagine a currency that was not silver or gold). By the 1860's they implemented paper money backed by gold and silver. Well into the 1900's they became a world currency and in the 1970's were no longer backed by gold. If you are expecting change to arrive in 10 years you best think your grandchildren and great grandchildren. We would all like it to happen sooner and maybe it will to some degree but 10 years is nothing in terms of changing the world.
