I find this first chart very interesting, as CR has aligned the Post WWII recessions at the point of greatest job loss. If The Obama Stimulus™ had actually worked, wouldn't there be a noticable uptick (that didn't include Census hires)?
People working part-time for economice reasons (also known as involuntary part-time) continues to stay high. These are the folks that lost their jobs, and have been unable to find full-time work. What concerns me about this data is that looking at the time periods for the last two post-recession, involuntary part-time stayed fairly high. From the 2001 recession, it never really flattened out. Perhaps "involuntary part-time" is becoming the new normal?
