MEGAN MCARDLE: “Everyone in the healthcare debate is looking for a villain: heedless consumers, careless doctors, grasping pharma companies. But the truth is, most of the increase in health care costs comes from new treatments, not abuse of the system.” Some of this will be solved by technology over time, as better, cheaper treatments replace marginally effective yet expensive ones. On the other hand, when you get a treatment for a disease that was hitherto untreatable, I suppose costs go up — since now you can do something, where before you couldn’t.
