Q: Why would the hospital have any right to order that the patient be removed from life support if the family protests that decision?
A: Because the medical care is financed by the government, so the government - in the form of a judge - can pull the plug.
But hey, no worries, I am sure that 21Steelers will be here momentarily to explain why giving control of medical care and medical decisions to the government could never go wrong. They are here to help us, right? Other than when they want to kill us, I mean.
