This is a chart of the labor participation rate since 2004:
The chart is from an article posted Friday at Doug Ross @ Journal. As you can see from the chart, the rate was a pretty solid 66 percent for the years 2004 through 2008. It began to drop in 2009 and has continued downward. The current low unemployment rate was obtained by not counting the people who have dropped out of the labor force. As you can see, there have been a lot of them since 2009. The bottom line here is simple–the economy is not recovering at this time. It is limping along and will be further limited by the President’s war on coal and other environmental decisions.
