Nauru is the smallest island nation in the world, a floating driblet of rock one tenth the size of Washington, D.C. Forty years ago, it was one of the wealthiest nations in the world thanks to rich, deep phosphate mines. Today, Johnny Colt reports for CNN, it has an unemployment rate of 90 percent.
