Even though more and more Americans have no health insurance at all, Americans consider health care to be a right. Not just that: We consider the best possible health care to be a right. Few would find it acceptable for a poor person to die of a medically curable disease for lack of money. Even fewer would find it acceptable that they themselves should die because the system won't spend the money to cure them. This is all in theory, of course. In practice, people die all the time because some effective treatment is too expensive. But whenever an issue gets drawn into the political system and becomes explicit, it becomes harder. That is what health-care reform will do to the question of rationing.
