The recession that ended three years ago this summer has been followed by the feeblest economic recovery since the Great Depression. Since World War II, 10 U.S. recessions have been followed by a recovery that lasted at least three years. An Associated Press analysis shows that by just about any measure, the one that began in June 2009 is the weakest. The ugliness goes well beyond unemployment, which at 8.3 percent is the highest this long after a recession ended. Economic growth has never been weaker in a postwar recovery. Consumer spending has never been so slack. Only once has job growth been slower. More than in any other post-World War II recovery, people who have jobs are hurting: Their paychecks have fallen behind inflation.
