"Australian mining magnate Gina Rinehart has criticised her country’s economic performance and said Africans willing to work for $2 a day should be an inspiration. Ms Rinehart is said to make nearly A$600 (£393) a second." The richest woman in the world is making an increasing number of public appearances, and speaking of increasingly controversial topics. I wonder why. It couldn’t be that she is becoming increasingly aggressive and controversial because her core business is in trouble, could it? Marc Faber suggests so: "There have been four mega bubbles in the past 40 years. In the 1970s it was gold; in the 1980s it was the Nikkei, and in the 1990s it was the Nasdaq. Bigger than all of them, though, has been the iron ore bubble, a tenfold increase in prices in less than a decade."
