Jack Welch, former head of GE (General), says there is something that does not add up in the Labor Dept numbers for unemployment in Sept. 2012 showing that the unemployment rate declined from 8.1% to 7.8%, because experts estimate the economy has to generate more than 150,000 jobs each month just to keep up with population growth. The number of jobs generated for 2012 are lower than this number. Another measure of unemployment which shows the underutilization of labor in America, which the U.S. Federal Reserve's Bernanke looks at because it is ameasure of how effectively the U.S. is using the productive resources of the country, is U-6. U-6 covers people in parttime jobs who cannot find full time jobs and this has remained unchanged at 14.7% for Sept. 2012 according to the Labor Department.
