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. āIf you look at a large hospital, I bet theyāve got more billing clerks than they do nurses, per patient,ā said Rogers. āThat tells you where the money is going; itās not going to health care, itās going to billing.ā
