There are information asymmetries in this story. Health insurance is limping along. It's limited in scope, and then you other consequences. Insurance companies have high premiums to protect themselves. The ones who come to the insurance company are sicker and the people have to pay more. You have adverse selection. You have moral hazard. And the doctor does what's on the safe side -- defensive medicine -- without regard to cost. These are fundamental conditions that make health insurance difficult. You have some things that help. Some doctors understand that they shouldn't abuse the system. But you still see problems in the way doctors behave towards patients. They goof off. Sometimes it's too much work. Some things are difficult and risky to diagnose. (Kenneth Arrow)
