In the realm of public policy, a bit of economic thinking can go a long way. Obamacare is seemingly grinding to a half as a result of being fundamentally at odds with basic economic principles. Today, real, acting human beings are much less the object of economics than are complex mathematical models, abstracted away from reality and setting aside the most central ideas of traditional political economy. And that's unfortunate, because economics as the study of human beings, their wants, and their means of acquiring them has much to teach about health care policy in general and the failures of Obamacare in particular.
