Well, the nurses came to this understanding first (like Donna Smith and Rose De Moro)... but it's good to see the medical doctors now on board.
This is so patently obvious that it's no wonder that the neo-liberal Hillary Clinton tried to discredit Mr. Sanders for saying pretty much the same thing, as if it were a mere pipe dream:
"The single-payer program would save about $500 billion annually by eliminating the high overhead and profits of insurance firms, and the massive paperwork they inflict on hospitals and doctors."
I waited out the Obama "care" debacle since my state (Florida) opted out, and to me the whole idea of putting an insurance for-profit corporation as middle man between any patient and their health CARE provider is abysmal and insane.
Since the cure to the problem exists and its only obstacles are the insurance companies and the politicians they bankroll, there's no reason why this intelligent use of public funds not establish health care for all.
A media that wasn't under corporate capture would help. Probably 40% of MSM ads refer to some drug that was recently designed to treat some condition that may or may not exist or be naturally occurring.
