The average American doctor now spends 14 percent of his income on insurance paperwork. A North Carolina doctor we interviewed had to hire four people just to fill out forms. He wishes he could spend that money on caring for patients.

The paperwork is part of insurance companies' attempt to protect themselves against fraud. That's understandable. Many people do cheat. They lie about their history or demand money for unnecessary care or care that never even happened.

So there is a lot of waste in insurance -- lost money and time.

Imagine if your car insurance covered oil changes and gasoline. You wouldn't care how much gas you used, and you wouldn't care what it cost. Mechanics would sell you $100 oil changes. Prices would skyrocket.

That's how it works in health care. Patients don't ask how much a test or treatment will cost. They ask if their insurance covers it. They don't compare prices from different doctors and hospitals. (Prices do vary.) Why should they? They're not paying. (Although they do in hidden, indirect ways.)

In the end, we all pay more because no one seems to pay anything. It's why health insurance is not a good idea for anything but serious illnesses and accidents that could bankrupt you. For the rest, we should pay out of our savings.

Next week, we'll look at alternatives to this crazy system.
