(U.S. labor force shrunk by 2.5 million jobs in January as compared to December of 2011, and labor force participation rate declined to 63.7 percent, a 30-year low; BLS report notes that there are fewer non-farm payroll jobs in the economy as of January 2012 than there were in 2000 despite the U.S. population increasing by 30 million over the same timeframe; BLS also notes that in 1980, less than 30 percent of all jobs were low-income while that number today exceeds 40 percent; due to shrinkage of labor force by 1.2 million (December to January), unemployment rate fell to 8.3 percent; unemployment rate 13.0 percent higher than what Obama Administration promised unemployment would peak at if 2009 "stimulus" bill passed; rate is 38.3 percent higher than what Obama Administration projected unemployment would be in February of 2012 if "stimulus" bill passed and 22.0 percent higher than what Obama Administration projected unemployment would be in February of 2012 if stimulus bill not passed; relatedly, Treasury Department reports that it collected $310 million more in withholding tax for first quarter of fiscal 2011 (Oct. 2010 - Jan. 2011) than it did in first quarter of fiscal 2012; reduced withholding collections could be as a result of fewer people paying (i.e., less employment) or increased employment combined with a shift to lower-paying jobs; thus, Obama Administration's claim that 243,000 jobs were created in January, if true, means that the jobs created were very low-paying jobs combined with the loss of some higher paying jobs).
