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. “If you look at a large hospital, I bet they’ve got more billing clerks than they do nurses, per patient,” said Rogers. “That tells you where the money is going; it’s not going to health care, it’s going to billing.”
