Krugman On Healthcare

It's not gonna get any straighter than this:

The key thing you need to know about health care is that it depends crucially on insurance. You don’t know when or whether you’ll need treatment — but if you do, treatment can be extremely expensive, well beyond what most people can pay out of pocket. Triple coronary bypasses, not routine doctor’s visits, are where the real money is, so insurance is essential.

Yet private markets for health insurance, left to their own devices, work very badly: insurers deny as many claims as possible, and they also tryto avoid covering people who are likely to need care. Horror stories are legion: the insurance company that refused to pay for urgently needed cancer surgery because of questions about the patient’s acne treatment; the healthy young woman denied coverage because she briefly saw a psychologist after breaking up with her boyfriend.

Still, most Americans do have health insurance, and are reasonably satisfied with it. How is that possible, when insurance markets work so badly? The answer is government intervention.
