Crisis of Abundance, by Arnold Kling, Cato Institute, 2006, p.31

George Mason University economist Robin Hanson offers another narrative.  Health Services are a way of showing the sick that we care about them, but on average they are not an effective way of improving the outcome because harmful care roughly cancels out ehlpful care at the margin.  he suggest that this narrative best explains the many studies that seem to show little difference in outcomes among different populations despite differences in expenditure.
