Only a single payer system can bring U.S. health care into the 21st century, said Dr. Susan Rogers, of Physicians for a National Health Program. Private insurance corporations drain society of health care resources. âIf you look at a large hospital, I bet theyâve got more billing clerks than they do nurses, per patient,â said Rogers. âThat tells you where the money is going; itâs not going to health care, itâs going to billing.â
