This summer marks the 60th anniversary of Medicare and Medicaid, the twin government programs that have shaped the health care system into what it is today. In this special episode, KFF Health News’ Julie Rovner interviews two experts on the history, significance, and future of these perennially popular programs. First up, Medicare historian and University of North Carolina professor Jonathan Oberlander. He’s followed by George Washington University professor Sara Rosenbaum, who not only has studied Medicaid since nearly its beginning but also has helped shape Medicaid policy over the past four decades.
