Cry for yourself, Argentina. What a shame to see a country of such great economic promise swerving off the road to prosperity again. The latest in a history of unforced errors began in 2007. National elections ushered in populist President Cristina Fernandez, who has led her nation to the brink of disaster by refusing to play by the rules of global finance. She restricted international trade, violated contracts and pumped out phony data to disguise the soaring inflation her policies brought about. All the while she scored cheap political points by blasting the rich countries of the north for their supposed economic imperialism.
