In the semi-euphoria over the declining jobless rate, one nagging statistic persists: Labor-force participation in the job market continues to slide.

Since the Great Recession began in 2008, 7 million Americans have dropped out of the labor force, and these individuals are not counted among the unemployed in the lower unemployment rate. Demographic factors explain about a third of the declining labor force participation (going back to school, early retirement, etc.) but the remaining number of unemployed-but-not-seeking-work remains alarming.
