The enormous number of people who work only part-time for economic reasons is one the tragedies of the unemployment crisis in this country. It didn’t even start with the financial crisis. Before the 2001 recession, there were a little above 3 million of them. By September 2003, as the economy recovered, there were 4.84 million. Gradually, part-timers got fulltime work, and their number zigzagged back down. In April 2006 dropped, it below 4 million, but only briefly, then edged up again. It never returned to the “normal” that was before the 2001 recession.
