The key thing you need to know about health care is that it depends crucially on insurance. You don’t know when or whether you’ll need treatment — but if you do, treatment can be extremely expensive, well beyond what most people can pay out of pocket. Triple coronary bypasses, not routine doctor’s visits, are where the real money is, so insurance is essential.
Yet private markets for health insurance, left to their own devices, work very badly: insurers deny as many claims as possible, and they also try to avoid covering people who are likely to need care. Horror stories are legion: the insurance company that refused to pay for urgently needed cancer surgery because of questions about the patient’s acne treatment; the healthy young woman denied coverage because she briefly saw a psychologist after breaking up with her boyfriend.
And in their efforts to avoid “medical losses,” the industry term for paying medical bills, insurers spend much of the money taken in through premiums not on medical treatment, but on “underwriting” — screening out people likely to make insurance claims. In the individual insurance market, where people buy insurance directly rather than getting it through their employers, so much money goes into underwriting and other expenses that only around 70 cents of each premium dollar actually goes to care.
Still, most Americans do have health insurance, and are reasonably satisfied with it. How is that possible, when insurance markets work so badly? The answer is government intervention.
Most obviously, the government directly provides insurance via Medicare and other programs. Before Medicare was established, more than 40 percent of elderly Americans lacked any kind of health insurance. Today, Medicare — which is, by the way, one of those “single payer” systems conservatives love to demonize — covers everyone 65 and older. And surveys show that Medicare recipients are much more satisfied with their coverage than Americans with private insurance.
Still, most Americans under 65 do have some form of private insurance. The vast majority, however, don’t buy it directly: they get it through their employers. There’s a big tax advantage to doing it that way, since employer contributions to health care aren’t considered taxable income. But to get that tax advantage employers have to follow a number of rules; roughly speaking, they can’t discriminate based on pre-existing medical conditions or restrict benefits to highly paid employees.
And it’s thanks to these rules that employment-based insurance more or less works, at least in the sense that horror stories are a lot less common than they are in the individual insurance market.
So here’s the bottom line: if you currently have decent health insurance, thank the government. It’s true that if you’re young and healthy, with nothing in your medical history that could possibly have raised red flags with corporate accountants, you might have been able to get insurance without government intervention. But time and chance happen to us all, and the only reason you have a reasonable prospect of still having insurance coverage when you need it is the large role the government already plays.
