Why markets can’t cure healthcare - Paul Krugman Blog - NYTimes.com
"This problem is made worse by the fact that actually paying for your health care is a loss from an insurers’ point of view — they actually refer to it as “medical costs.” This means both that insurers try to deny as many claims as possible, and that they try to avoid covering people who are actually likely to need care. Both of these strategies use a lot of resources, which is why private insurance has much higher administrative costs than single-payer systems. And since there’s a widespread sense that our fellow citizens should get the care we need — not everyone agrees, but most do — this means that private insurance basically spends a lot of money on socially destructive activities."
There are a number of successful health-care systems, at least as measured by pretty good care much cheaper than here, and they are quite different from each other. There are, however, no examples of successful health care based on the principles of the free market, for one simple reason: in health care, the free market just doesn’t work. And people who say that the market is the answer are flying in the face of both theory and overwhelming evidence.
