Answers for the future of health care?
The answer to the first problem, the variability and absolute nature of risk, is clearly to spread the risk over all who share it, even if it is invisible to them. If you drive a car, you must have car insurance, and your gas taxes contribute to maintaining the infrastructure of roads and bridges; if you own a home, you must have fire insurance, and your property taxes pay for the fire department. Because of your ownership and use of these things, you not only must insure yourself against loss, you also must pay part of the infrastructure costs that your use of them occasions. Similarly, all owners and operators of human bodies need to insure against problems that may accrue to their own body, and pay some of the infrastructure costs that their use of that body occasions. However the insurance is structured and paid for, somehow everyone who has a body needs to be insured for it - the cost of the risk must be spread across the population.
Skipping to the third problem, the infrastructure argument, its answer is somewhat similar: To the extent to which health care capacity is infrastructure, like police, fire, ports, highways, and public education, the costs are properly assigned to the society as a whole; they are the type of costs that we normally assign to government, and pay for through taxes, rather than per transaction. In every developed country, including the United States, health care gets large subsidies from government, because it is seen as an infrastructure capacity.
That leaves the second problem, the way in which all demand apes the absolute nature of true demand in health care ("Get this or die"). The answer to this problem is more nuanced, because it is not possible to stop depending on the judgment of physicians. Medical judgment is, in the end, why we have doctors at all. But we can demand that doctors apply not just their own judgment in the moment, but the research and judgment of their profession. This is the argument for evidence-based medicine and comparative effectiveness research. If a knee surgeon wishes to argue that you should have your arthritic knee replaced when, according to the judgment of the profession as a whole, the better answer in your situation is a cortisone shot and gentle daily yoga, the surgeon should have to justify somehow, even if just for the record, why your case is different and special. The physician's capacity to make a buy decision on your behalf must be restrained at least by the profession's medical judgment. If the best minds in the profession, publishing in the peer-reviewed literature, have come to the conclusion that a particular procedure is ineffective, unwarranted, or even dangerous, it is reasonable for insurers, public or private, to follow that best medical judgment and stop paying for it.
These three core factors - the absolute and variable nature of health care demand, the complexity of medicine, and the infrastructure-like nature of health care capacity - are all endemic to health care and cannot be separated from it. And all three dictate that health care cannot work as a classic economic response to market demands. Failure to acknowledge these three core factors and structure health care payments around them account for much of the current market's inability to deliver value. Paying "fee for service," when the doctor is both the seller and acting as agent for the buyer, and when the doctor is punished for doing less, is a prescription for always doing more, whether "more" delivers more value or not. Paying "fee for service," unrestrained by any way to make classic value judgments, means that hospitals and medical centers respond to competition by adding capacity and offering more services, whether or not those services are really needed or add value.
For all these reasons, it is vastly more complex to structure a health care market rationally, in a way that delivers real value, than it is to structure any other sector, and simply fostering "free market" competition will not solve the problem.
