It doesn't. It covers unexpected health bills, which is a very different thing.
Any type of situation that is expected to happen can not be covered by insurance, it needs to be covered by savings instead.
However many people want insurance premiums to be a type of forced savings plan, which is why there is such a huge argument in the US about health insurance.
Those opposed to government regulation want to handle the savings on their own. Those who like government regulation want it to force people to save for health care costs.
Part of the philosophical idea behind single payer is that people have minimal control over financially devastating illness and injury, and one thing society can do that individuals can't is allow everyone to share the risk, transforming a small probability of an untenable expense into a certain probability of a manageable expense.
You're right, and usefully so, to point out that private health insurance is treated like a utility instead of an insurance plan; knowing that also allows consumers to select high-deductible plans, and to take advantage of HSAs for tax-advantaged funding of the health care bills they do expect.
But single-payer insurance can handle both problems (routine billing and catastrophic coverage) coherently.
The transformation of insurance into a savings scheme puts considerable distortion on that model. It becomes impossible to see what payment is for expected treatment, and what is for risk assignment. The model then encourages people to use more ("I've already paid for it") and to pay no attention to cost. And it encourages the attitude that any problem should be paid for. It's hard to exaggerate the impact of these effects on health care's crazy cost structures.
The real problem isn't people who are riskier, it's people who are costlier. Someone with a prior condition isn't a risk, they're a cost. Insisting they should have "access to insurance" is simply insisting on cost redistribution. The circumstances under which that cost redistribution is a good idea socially should be an entirely different question than the efficient structure of health care payments.
These concepts are deliberately obscured by the political rhetoric around "health insurance", precisely to obscure the cost shifting nature of the project and to create a sensibility that the problems is somehow the greed of financiers. (Obscuring the cost drivers is also a goal, it's a very large industry that employs a lot of people, many of whom, at many levels, stand to lose a good deal if the system were ever seriously rationalized.) It's a very effective rhetorical strategy, especially given the abstractions around risk, but it shouldn't be confused with an actual discussion of the economic problem.
What "society" (government) can do is force everyone to share THE SAME risks
single-payer insurance == monopoly
It's not hard to make a list of "freedoms" we're mostly happy that people give up: the "freedom" to drive 100mph through school zones, the "freedom" to sell patent medicines with Pfizer branding on it, the "freedom" to set tire fires on our lawns. Those "freedoms" are respectively outweighed by the cost of collisions, of medical fraud, and of toxic and repulsive clouds of smoke.
When societies adopt single-payer health care systems, they're expressing a judgement that the "freedom" to take individual control over how to finance health care at the lowest possible price is outweighed by the cost to society of the uncertainty of health care costs.
And, setting aside principle for a moment, your health & well being is in fact one of the most important uncertainties in your life. You could be hit by a bus tomorrow, or stricken with a disease that outstrips your ability to pay for care. With the exception of a tiny, tiny fraction of people in society, nobody can truly provide an assurance of their ability to provide for their own care. So, to bring the principle back into the picture: if you're ideologically opposed to single-payer or socialized or mandated health insurance, it would seem that you must also support the idea that people who can't pay for their care must be denied care.
There's a wide variety of pragmatic objections to single-payer insurance, many of which are probably valid. But if we're going to bring "freedom" and "choice" into the picture --- ideology, in other words --- we should be clear about what the tradeoffs are.
I see conservatives (not trying to label you) make this argument a lot, and I think it is a mischaracterization of 1) what most people mean by health insurance, and 2) what health insurance and health plans are really about: pooling risk and creating groups that can negotiate for lower prices.
Re. 1: just skim the wikipedia article for health insurance (http://en.wikipedia.org/wiki/Health_insurance); the distinction between health plans vs. what you mean by "health insurance" all gets rather confused.
The fundamentals of the system we're moving towards in the US is actually a conservative plan from the '90s: an exchange-based market for private health insurance coupled with guaranteed issue and a mandate for coverage. That plan was itself a response to the original liberal vision of universal health insurance: nationwide government-run single payer insurance.
Yeah right. Until you run out of money. Then what?
In your world, you die. Good for everyone, until it's you or someone you care about. Then, like everyone else, you off running to the SS office to apply for (Medicare) disability.
The whole point of insurance is to protect against risk. Else why have it at all?
Not to be pedantic but I will stand on a soapbox for a moment: I'd also point out that we all have the ability to care for our health. Health care is a daily activity which requires no insurance, and often no cost.
Risk carries an element of unpredictability. If a scenario is predictable, there is no risk to be shared, ergo by definition a scenario with little risk (e.g. known diagnosis and treatment plan) is absolutely and unsurprisingly not fitting for insurance.
Did I miss something?
Quoting from the article: Hendren didn’t invent the idea of markets falling apart because customers know something that companies don’t. Nobel prizes were awarded to a trio of economists in 2001 for developing this idea of adverse selection in the 1970s. But his use of the concept may at least partly resolve the puzzle of why those with pre-existing conditions can’t get insurance.
Another quote: This individual mandate is a natural fix to the problem of adverse selection in health insurance: It keeps the lowest-cost participants from opting out, and as a result the market doesn’t unravel.
The "ignorance" is in "likelihood of utilization", not "cost of utilization".
(Personally, I would never use private health care in the UK. I know people who have.)
If you can't opt out, then choosing private basically means paying for both.
It's true that every health care system rations care. The difference is that a universal system rations based on medical need (triage) whereas a market system rations based on ability to pay.
It also clearly demonstrates one of the reasons why markets alone are simply not sufficient/appropriate for some problems. The rest of the developed countries outside of the US have long understood this with respect to health care.
Do 300M people really have to negotiate their own insurance, and research carefully all the terms and conditions and so on?
Why do you single out health insurance?
I know that health insurance is often used to teach asymmetric information models, but it wasn't always obvious that it's a good example. Someone selling a used car might know a lot more about the car's hidden costs than anyone else, but does the typical buyer of health insurance really know more about his or her probability of illness than a sophisticated insurer with good doctors and actuaries and a lot of data?
This led some economists to argue that the problem in health insurance markets is not asymmetric information, but rather too much information—the insurer already knows you will be a bad risk. This research makes it clear that there really is asymmetric information and spells out what it is.
Your ideal universal system may ration on medical need. There might even be one in existence that does so...
...but I really doubt it.
The WP article later says: "On the other hand, "positive" test results for adverse selection have been reported in health insurance,[8] long-term care insurance[9] and annuity markets.[10]". The reference #9 is Finkelstein, A.; McGarry, K. (2006). "Multiple dimensions of private information: evidence from the long-term care insurance market". American Economic Review 96 (4): 938–958.
Then if you go to the actual paper by Nathaniel Hendren, linked to by the Slate article, you'll read:
"""Previous research has found minimal or no evidence of private information using the revealed preference approach in these settings. In life insurance, Cawley and Philipson [1999] find no evidence of adverse selection. He [2009] revisits this with a different sample focusing on new purchasers and does find evidence of small amounts of adverse selection. In long-term care, Finkelstein and McGarry [2006] find direct evidence of private information by showing subjective probabilities are correlated with subsequent nursing home use. However, they find no evidence that this private information leads to adverse selection in the form of a correlation between insurance purchase and subsequent losses in the LTC insurance market.35 To our knowledge, there is no previous study of private information in the non-group disability market."""
In other words, WP's "'positive' test results" isn't as strongly positive as you might think from that short WP summary. The finding from this paper is the development of a more useful model of the problem which can make more concrete statements like: "For those who would be rejected, private information imposes a barrier to trade equivalent to an implicit tax on insurance premiums of roughly 65-75% in long-term care, 90-130% in disability, and 65-130% in life insurance."
That could not have been done using the information in the Wikipedia article.
You complained about two things: that there are no new findings, and that the Slate article could have been writing from the Wikipedia article. I think I've shown that there are definite new findings in the actual report. It was interesting enough, after all, to get the researcher "offers from economics departments at Harvard, Stanford, and Princeton."
As to the quality of the Slate article - the entire first half is meant for someone who has never heard of "adverse selection", and it explains the topic much better than the WP article does. It then covers some of the research methodology, and describes the policy impact and ties to changes in US insurance law and politics. None of the last half is covered in the Wikipedia article.
Setting aside the question of market vs. socialized health care, it doesn't take much observation to realize that this is a very bad system. It both sweeps costs under the carpet and removes consumer choice from the equation, thereby severely reducing the extent to which health insurance companies must compete on both cost and quality of service.
Think your company's group plan is too expensive? Well, you're free to drop out of it if you want. Of course, the money they were spending on your health insurance won't get added to your salary when you do, so ultimately whatever you find will end up being even more expensive.
Pissed off because your health insurance company screwed you over? Well, you've got pretty much the same "my way or the highway" option.
What a lot of folks fail to realize is, just because we don't have a socialized system doesn't mean we have a market system. What we actually have is a bastard system that offers the benefits of neither, plus some downsides that are uniquely its own.
That system is in fact not too far from what we're trending towards in the US.
And "guaranteed issue" is never _insurance_, it's cost sharing. Because it takes the known costs of some individuals and spreads them to others. It is a mandated subsidy. Doing it through "insurance" introduces opacity into the system, which obscures from the electorate the costs of the choices they're making, and reduces accountability throughout the entire system.
You are articulating the "moral hazard" concern with universal health insurance. I am recognizing moral hazard, and saying that it can be addressed in a universal system simply by setting the threshold that the system pays out at a higher number.
So the freedom we're really talking about is --- notionally --- the freedom to make what basically must be an irresponsible choice.
It's true; single payer systems do create a monopoly for health care funding; that monopoly takes its place alongside the monopoly for military force, for air traffic control, for fire prevention, for oceanic weather surveillance, &c.
I don't think this is a significant problem, because the people who receive this subsidy vastly outnumber the people who provide it.
Edit: A liver transplant is a procedure with a very high expected value in terms of QALY/USD. Americans in aggregate spend a great deal of money and effort on procedures with very low expected QALY/USD. Some people, myself included, would prefer not to purchase a procedure with very low expected QALY/USD.
There was a good discussion on a similar subject earlier: http://news.ycombinator.com/item?id=3313570
That's true, but it's not a winning argument.
"Part of the notion that suggests people should be forced into sharing those risks is that nobody can rationally rule out future unbounded <whatever> expenses; you can't predict the future, and virtually nobody has enough money to cover every plausible <whatever> expense they might face."
Meet socialism.
56% get it from their employer, and 8% buy their own private insurance.

I believe his argument is that expensive end-of-life care is unnecessary because death at that point is inevitable in the immediate future. You can gain months on average, but those months aren't economically invaluable.
With limited resources, its better to spend on treatments with the greatest quality of life to cost ratio.
I sincerely don't understand why people call it "free market".
