Here’s a good debate from December 5, 2017 on the subject.
Is single payer the next step in American health care? What alternative approaches can we explore? The Dole Institute Student Advisory Board will examine differing systems and the future of U.S. health care policy with special guests Dr. Joshua Freeman and Dr. Josh Umbehr. Freeman is professor emeritus at KU Medical Center, while Umbehr is a KU School of Medicine graduate and the owner of Atlas MD.
My bias is obvious.
