Congress has failed to get at a root cause of our rising health insurance costs. We must confront obesity and unhealthful eating to save lives and cut cost.

If your home got hit by a tornado, no one would tell you you should have done more to prevent it. Our health problems are not that simple.

They break down into three types: Type One are unlikely problems you don’t anticipate. Type Two are problems you expect but can’t do much about. Type Three are problems you could have prevented or greatly reduced the probability of.

Everyone agrees we should pay for insurance for Type One problems. Most people agree with paying for Type Two. But why should we all have to pay for Type Three?

Some people take wild and reckless chances with their health. They expose themselves to all sorts of dangers, eat lots of unhealthful things and avoid exercise.

To make matters worse, once covered by health insurance, they do even more unhealthful things. This last bit is what economists call the “moral hazard” of insurance. Moral hazard simply means that you increase the risky behavior you are insured for just because you have insurance.

A basic principle of economics is that you pay for what you get. The costs are directly associated with the corresponding benefits. In principle insurance deviates from this only in the sense that the premium you pay should be directly associated with the expected benefit.

If your house is more expensive to replace, or you live in a more tornado-prone area, you can expect to pay a higher premium.

Health insurance follows this same basic principle for problems under Type One, which are essentially just bad luck. For Type Two the problems can be foreseen but are uncontrollable, such as a woman with a gene that puts her at high risk for breast cancer.

Here many of us would agree to redistribute the costs of this type of misfortune. It’s not her fault. She was born that way. Give her a break.

The real issue is with Type Three. These people could have prevented or at least reduced the probability of health problems. But they didn’t. Worse yet, many of them increased their unhealthful behavior, taking advantage of the rest of us and making us pay.

This moral hazard problem violates the principle that you pay for what you get. It is a key source of our rising, out-of-control health care costs.

This has nothing to do with some nanny state trying to tell you how to live your life. We don’t care if you want to smoke like a fiend, drink yourself into a stupor and eat Ho-Hos and Ding-Dongs like there’s no tomorrow. (Actually some of us do care, but that’s not the point.) We just don’t want to pay for your unhealthful behavior.

Conservatives (not to mention liberals) have to face the fact that someone has to pay if we are going to have health insurance (either public or private). If the word “taxes” is too upsetting, just call it a “premium adjustment.”

We need to call upon a panel of medical experts to construct a list of unhealthy foods. There could be several categories from extremely bad to just plain bad. We need to apply the “premium adjustment” (aka federal sales tax) to these foods and other unhealthy consumables.

It may not be feasible to determine how much exercise you’re getting or how recklessly you drive your car, but we certainly can do something about all the bad food people eat, which is driving up our health care costs.

Now is the time to impose a federal sales tax on unhealthful food. To compensate the poor and reduce calories, food stamps should count double when purchasing unprocessed fruits and vegetables.

Congress must pass a health insurance law that gets at this root cause of rising health costs.
