There are currently more than 4 million Americans who have been unemployed for 27 weeks or more. This figure doesn’t include those who work part-time or on contracts — or those who, discouraged, have simply stopped trying. Many of them are older and well educated, and their situation doesn’t seem to be improving despite America’s slow crawl out of the recession. While last week’s jobs numbers extolled a decline in the national unemployment rate, the numbers for the long-term unemployed didn’t even budge.
