And yes, before I get started, I agree with the vast majority of the commenteriat here that absent massive path dependency and being able to make policy behind a veil of ignorance, I would not choose the US model or the modifications to the model that are being made by Obamacare. I would have chosen a far more comprehensive single payer system that is not a kludge of multiple previous kludges. However, that is not the world that we live in, so I am assuming profit seeking insurance companies will be around for a while.
There are two things worth noting here. The first is that he concedes (as does anyone with any experience in the healthcare delivery system or the healthcare insurance industry) that a single payer system is superior to what we have and what the ACA provides. The second is a false statement that you, Scott, and other supporters of the ACA repeat sic ad nauseum. "However, that is not the world that we live in ..." Canada didn't "live in that world" either when they switched. Saying, "We can't do it here" is just, well, idiotic. All it takes is leadership. And I'll grant we are leaderless.
