University of Chicago professor John Cochrane has a Bloomberg View piece about health care:
Health care is a complex service, in which each person's needs are blurry, and the line between "need" and "want" blurrier still. Imagine if the government decreed that law firms, car-repair shops, or home contractors had to charge everyone the same price, and couldn't turn anyone away. "House fix," for example, would be $1,000 per year, no matter how large the house or what shape it's in. Why do we think this will work for medical services?
