Living on the Edge: Bill Moyers tells the story of several hardworking Milwaukee families struggling with low-paying jobs after previous employers downsized their operations. Filmed over a period of five years, these families were first featured in Moyers’s 1992 documentary ‘Minimum Wages: The New Economy.’ FRONTLINE chronicles the families’ emotional and financial strains, their search for better jobs and job retraining, and looks at Milwaukee’s efforts to adapt to an ever-shrinking industrial sector.
