Men Not Working, and Not Wanting Just Any Job - New York Times

"Despite their great numbers, many of the men not working are missing from the nation's best-known statistic on unemployment. The jobless rate is now a low 4.6 percent, yet that number excludes most of the missing men, because they have stopped looking for work and are therefore not considered officially unemployed. That makes the unemployment rate a far less useful measure of the country's well-being than it once was.
