“It is an occupational hazard for politicians to think that they and their ilk know best, and by all indications Mr. Obama rather likes centralization. In my professional lifetime in the centralized British health-care system, however, I have seen a hundred schemes of cost reduction, but I have never seen any reduction in costs, or at least any that lasted more than a few months. I can’t remember a single health minister who did not promise more efficiency at less cost, or a single one who actually managed to achieve it.”
