A study by Princeton University Professor Henry Farber reports that people in the US who lost jobs in the recession and found new ones made an average of 17.5% LESS. The average length of time people are unemployed in the US has steadily risen. In December 2007, the average length of unemployment was 16.6 weeks. In June 2009, it was 24.1 weeks. In September 2011, it was 40.5 weeks, the longest in more than 60 years.
