Currency Wars: A Fight Everybody Wins

Currency wars get a bad rap. The trouble starts with that second word. Wars, as we all know, are very bad. And a currency war -- where countries compete to lower their exchange rate to boost their exports -- reminds people of the kind of trade protectionism that killed some economies in the 1930s. But currency wars are the best kind of war. Nobody dies. Everybody can profit. In fact, currency wars didn't contribute to the Great Depression. They ended it.
