Understanding Insurance

It is clear to me from reading public reaction to arguments made in the Supreme Court this week on the constitutionality of the new healthcare law, that many people do not understand the concept of insurance.

Insurance is a means for a group of people to share the financial burden from losses that are unpredictable for the individual members, but predictable for the group as a whole. All members of the group contribute to a pool of money that is used to pay for individual losses when the need arises. Insurance is not a means for getting other people, corporations, or governments outside of the group to pay for losses. It is the members of the group that pay for losses and share in the benefits.

Insurance agreements work best when the loss events are truly random occurrences for individuals, but have well known probabilities so that the loss rate for a large population is a known quantity. I cannot know for certain if my house will be struck by lightening this year, but I do know that it is a certainty that someone's house in my community will be struck by lightening. If everyone contributes a small amount to an insurance pool so that the total equals the expected communal cost of lightning strikes, then those that do experience lightening strikes will not suffer a catastrophic loss. Not knowing who among the group will suffer a loss that is almost certain to occur, motivates everyone to contribute to the insurance pool.

Unpredictability is what makes an insurance contract possible. Whenever loss events become predictable, the entire concept breaks down. There are two ways that predictability can enter the system.

•People's behavior: The likelihood of an auto accident is partly random and partly the result of a driver's skill and tolerance for risk. Because these traits tend to correlate with demographics, market pressures arise for insurance pools to either exclude, or demand higher payments from people who fit certain demographic profiles. As a result, teenage boys pay more for auto insurance than middle-aged moms. A person with a history of traffic infractions and accidents might not be able to purchase auto insurance. Even though in the auto insurance market people are treated differently solely because of age, gender, and prior history, these pricing practices are not considered discriminatory.

• Past events: Obviously you cannot insure the past or else no one would contribute to the insurance pool for the future. Unlike the future, the past is entirely predictable because it has happened. No state would sell lottery tickets after the drawing. No bookie would accept bets on a football game after it has been played. No auto insurance company will sell a policy to someone after that person crashed. If this were allowed all these businesses would be broke in a matter of weeks.

I feel like I am stating the obvious, but many people in the healthcare debate do not understand these points. My people are outraged that the new law forces everyone to buy health insurance, and at the same time support the provision in the law that forbids insurance companies from denying coverage to people with pre-existing conditions. But if no one bought health insurance until it was needed, no pool of money would exist to pay for claims. The insurance model would breakdown quickly and no one would have insurance. The belief that it is possible to have universal healthcare coverage without a universal mandate to contribute is completely irrational.

In fact, without the new healthcare law the insurance model will breakdown in the near future. Too much concerning an individual's need for healthcare is predictable. Age and prior history are big factors in predicting healthcare costs for an individual, and just like for auto insurance, market pressures have arisen to exclude older and sicker individuals from insurance pools, either by barring them or pricing the insurance out of reach. But, unlike auto insurance, for which most states mandate coverage in order to drive, there has not been a health insurance mandate, so there is little incentive for the young and healthy to contribute to insurance pools that pay the cost of care for the aged and ill. Financing the healthcare system through a patchwork of private insurance plans simply isn't working because the predictability of the need for healthcare undermines the entire concept of insurance.

Opponents of the new healthcare law argue that mandated health insurance is different from mandated auto insurance because people can choose not to own or operate motor vehicles. Therefore it is possible to opt out of paying for auto insurance. But the irony is that as a consequence of our mortality, the need for healthcare is truly universal. Even though many people would prefer not to pay for health insurance and to opt out of the healthcare system, that choice is not possible. Almost everyone will need healthcare at some point in his or her life and federal law already requires that emergency rooms treat all patients. That means that healthcare is already socialized.

Unfortunately the emergency room is the most expensive and inefficient place to provide healthcare, and many uninsured are using emergency room services and not paying because they have no other choice. This practice further drives up insurance costs for those that do pay and prices more people out of the health insurance market. The current system is spiraling out of control. Eventually when so few people are insured that the healthcare system can no longer cover its overhead, it will experience a financial crisis with an unpredictable outcome.

The demand for healthcare is universal and government works best when addressing universal needs. The ideologues who denounce all government interventions ignore the fact that without government action there would be no Interstate highway system, no universal electrical service, no universal phone service, no Internet, no national defense, and the list goes on. Private enterprise could not have provided these services that we regard as essential to the modern functioning of our society. The loud voices denouncing all government intervention in the marketplace ignore reams of facts. Conservatives may long for a simpler past, but I doubt many of them would be willing to go back and live in the past, and give up all the modern conveniences they take for granted today.

Obama's affordable healthcare law is not a perfect solution, but first attempts to solve complex problems always need modifications. Scrapping the law and doing nothing leaves in place a healthcare financing system that is unsustainable. It is time to stop the shouting and have a serious, informed, and reasonable discussion on how to move forward with our nation's healthcare policies. Unfortunately in our current political climate, characterized by fear mongering, rigid ideologies, insatiable greed, and blind irrationality, I don't see that happening.
