Medicine may be hard, but health insurance is simple. The rest of the world's industrialized nations have already figured it out, and done so without leaving 45 million of their countrymen uninsured and 16 million or so underinsured, and without letting costs spiral into the stratosphere and severely threaten their national economies.
Even better, these successes are not secret, and the mechanisms not unknown. Ask health researchers what should be done, and they will sigh and suggest something akin to what France or Germany does. Ask them what they think can be done, and their desperation to evade the opposition of the insurance industry and the pharmaceutical industry and conservatives and manufacturers and all the rest will leave them stammering out buzzwords and workarounds, regional purchasing alliances and health savings accounts. The subject's famed complexity is a function of the forces protecting the status quo, not the issue itself.
PPACA my ass.
