President Bill Clinton signed a law he promised would "change welfare as we know it," partly with new emphasis on putting people to work. The idea was that, in times of crisis, states would still get families back on the rolls. But it's not working out that way. "Despite soaring unemployment and the worst economic crisis in decades, 18 states cut their welfare rolls last year." That was a lead sentence this week in the New York Times. Jason DeParle wrote the story.
