Eric Novack comments on the difficulties of a single-payer system:

. . . single payer advocates like to have it both ways. On the one hand they speak of inability to get care, while simultaneously decrying that up to 50% of care is unnecessary. Which is it? Or is it both? And, again, how is it that an unelected bureaucracy, given complete authority over what care you can choose to purchase with your own money, do a better job of both MAKING people take the doctor’s advice, while simultaneously preventing the 50% of care they think is uneeded? Again, single payer advocates have no answer for this other than a’panel of experts’ that will be immune from criticism from individuals, but highly susceptible to the money and efforts of aggressive lobbyists.
