It seems to work for the whole, entirety of the rest of the developed (and most of the developing) world, because the truth is socialized medicine is cheaper and more efficient.
Further, even if it wasn't cheaper, the value gained from a more efficient allocation of labor (due to the reduced friction from healthcare concerns) more than repays the costs of the healthcare.
I'm getting sick of people advocating inefficient capitalism as a good economic policy -- and that's all you're doing with your weird, social darwinist approach.
