Even with the massive 2008-2009 policy effort that successfully prevented financial collapse and Depression, the United States is now half way to a lost economic decade. Over the last 5 years, from the first quarter of 2006 to the first quarter of 2011, the U.S. economy’s growth rate averaged less than 1 percent a year, about like Japan during the period when its bubble burst. At the same time the fraction of the population working has fallen from 63.1 to 58.4 percent, reducing the number of those with jobs by more than 10 million. The fraction of the population working remains almost exactly at its recession trough and recent reports suggest that growth is slowing.
