Over the past decade, many media articles have discussed the topics of "Coutsourcing" and "Cemerging markets", voicing concerns about U.S. deficits and debt and the impact on the U.S. dollar. Gold prices have increased, commodity prices have soared, and there has been an explosion of exchange traded funds (ETFs), many that allow individual investors to "Cinvest" in foreign urrencies. As recently as mid-September 2010, the Japanese yen, for example, reached a 15-year high in value against the U.S. dollar.
