1. No Health Insurance. If you get sick or have an accident you pay for care out of pocket, until you exhaust your resources and go bankrupt. In the real world after this happens someone else picks up the tab for your care, see my post on EMTALA, but let's make this interesting. Suppose that you don't get any care after you run out of money.
2. Catastrophic Health Insurance. If you get sick or use medical care you have to pay a large amount of money out of pocket before your insurance plan starts to pay for health care. By a large amount of money, I mean maybe 20% of your income. After you reach this amount you will probably still have to pay additional amounts for care.
3. Complete Coverage. You may make small payments per service but everything is basically paid for.

The plans are listed in order of increasing cost. Plan 1 is free and plan 3 is the most expensive. Which do you want?

Now Wonks Anonymous will use his psychic powers to tell you something about your age and the state of your health. 

If you chose plan 1 you are likely to be quite young and probably as healthy as a horse. You may believe, deep down inside, that you will live forever. You may just make the calculation that someone will pay for your care if something bad happens. Or you may just be very wealthy.

If you chose plan 2 you are probably healthy and in your twenties or thirties. You are as yet unfamiliar with the many wonderful feature of the aging human body but you may participate in slightly risky sports or know some people who have had serious illnesses or accidents.

If you chose plan 3 you are either timid, as Wonks Anonymous was in his youth, or more advanced in years and physical maturity, as Wonks Anonymous is now. You know a bit about what health care can cost and you don't fancy being ill and poor at the same time.

Now you probably made your choice thinking that it would be, in the words of that great song from Avenue Q, "for now". You might have thought that, as you got older or if you got sick, you could always go to plan 3. There is a problem with this: If only old, sick unattractive people like yours truly choose plan 3, the average cost of medical care per person in this plan will be quite high. Unless you make very good investments now, you might not be able to afford plan 3 when you find out you need it.

And, unless you intend to die young and leave a beautiful corpse, Wonks Anonymous can assure you that you will need plan 3. So lets try this question again. Suppose that you have to choose now for the rest of your life. You can't change your mind later. Now which plan do you want?
