"Over the past quarter century, the global economy has doubled every 10 years, going from $31 trillion in 1999 to $62 trillion in 2008. Recessions have become tamer than ever before, averaging eight months rather than two years. More than 400 million people across Asia have been lifted out of poverty. Between 2003 and 2007, average income worldwide grew at a faster rate (3.1 percent) than in any previous period in recorded human history. In 2006 and 2007—the peak years of the boom—124 countries around the world grew at 4 percent a year or more, about four times as many as 25 years earlier."
