I wasn't trying to say Govt should or should not be in health care. (In fact they already are – VA hospitals, Medicare, Medicaid, etc.) That argument has been done and redone. No new points to be made there.
My point is the cost will be huge no matter what. Nice to say let's hold people accountable. But are you ready to let a fat guy die when he has a heart attack, a diabetic die when their legs turn gangrenous, and a meat lover when he has a stroke? I'm not. So, how do we make them accountable? And how much can we afford, no matter who is the final payer?
