This week, hosts Mark Masselli and Margaret Flinter speak with Dr. Elisabeth Rosenthal, editor-in-chief of Kaiser Health News and author of "An American Sickness: How Healthcare Became Big Business and How You Can Take It Back", a critical look at the high cost of American health care. Dr. Rosenthal examines the evolution of the profit driven American health system, and the role patients can play in re-gaining control of some of these costs.
