by Jason Breslow and Evan Wexler, Frontline, PBS For many middle-class families, the American Dream can feel as though it's slipping away. For others, it can seem lost for good. Consider Terry and Tony Neumann and Claude and Jackie Stanley -- the two Milwaukee couples featured in an episode of FRONTLINE, Two American Families. In 1992, both Tony and Claude had recently lost their manufacturing jobs. For the next 20 years, our cameras followed them and their families as they struggled to avoid poverty. When they could find work, it was often for longer hours, less pay and no benefits. Bills piled up, tensions rose and relationships became strained. Of course, their story is far from unique. Over the last several decades, the middle class has struggled to keep pace with smaller paychecks, mounting debt and shrinking opportunities for steady work. The following eight charts offer a brief snapshot. http://www.pbs.org/wgbh/pages/frontline/business-economy-financial-crisis/two-american-families/the-state-of-americas-middle-class-in-eight-charts/
