A disturbing pattern has emerged in my discussions with people who support Obama Care: They do not know what insurance is and how it works.
I will try to make it simple enough so that even someone with a sociology Ph.D. can understand it.
An insurance policy is a contract between two parties: One party, let's call her Alice, agrees to pay a small amount every month. The other party, say Barb, agrees to cover Alice's costs if a specific bad thing happens.
For example, Alice might agree to pay $100 every month, in exchange for Barb paying $100,000 if Alice's house burned down.
Why would Barb agree to this? I can hear you scream already.
Well, Barb would agree to this contract only if:
- the probability of one's house burning down was small enough
- the probability that one's house burned down did not depend on whether one has insurance
- and, there were many people like Alice
Barb can make money by collecting premiums which she then invests in other assets to earn a return. Barb's main outlays are payouts to people whose homes have burnt down and the costs involved in checking the validity of claims. In years when very few houses burn down, Barb makes a lot of money. In years when many houses burn down, Barb makes less or even loses money.
If Barb did not do a good job of verifying that claims are valid, she would go bankrupt very fast: Anyone whose home was worth less than $100,000 in the market would burn it and collect $100,000.
For Barb to be able to offer an attractive contract, the probability of one's house burning down must be fairly small. Otherwise, the premium would have to approach the actual damage amount which would mean people would find self-insurance preferable.
Of course, the whole thing only makes sense if Barb can get many people like Alice to pay $100/month to actually be able to cover a reasonable amount of claims every year.
For example, if Barb had 10,000 customers, and the probability of a house fire was 1% for each client and house fires were completely random and independent of each other, Barb would expect to pay on average 100 claims a year, and it would be relatively unlikely to have years with fewer than 70 or more than 130 claims (trust me ;-) So, with a premium of $100/month for every customer, Barb would pay out less than it collected in premiums and have money left over in years with fewer than 120 fires. The left over money can be used to add to reserves and investments and cover operating costs.
Why would Alice do this? Because if she is not rich enough, a house fire like that would wipe her out. She would buy the insurance if the premiums are low enough that permanently giving up part of her income stream in return for not being completely wiped out in the case of a fire.
Pre-existing Conditions
Say, Carl chooses not to buy insurance. One day, lightning hits his house and it burns down. Does it make sense for him to be able to go buy insurance from Barb, put down the first month's premium of $100, and have Barb pay him $100,000?
Of course, everyone would love to be able to avoid paying any premiums until something bad happens and get all one's expenses covered for a puny sum.
The question is, can there be insurance in a world where Barb is required to give Carl 99,900 dollars of her other customers' premiums in return for his $100?
After all, all Barb has are the premiums she collects from people who purchase insurance (the answer does not change if Barb is, say, a Kennedy and independently wealthy — it would just take longer to ruin Barb in that case). If one could buy insurance after the house has burned down, everyone would do it because one would save all those "unnecessary" premium payments and spend them on other things one likes.
That means, every morning, Barb might have some new customers at the door whose homes had just burnt down. With their $100 bills in their hands, they would demand that Barb pay them $99,900. If Barb cannot legally reject them, Barb's liabilities would far exceed her assets and she would have to get out of the insurance business and start making, say, abstract art in San Fransisco and hope that Ms. Pelosi would buy enough of it.
Faced with this simple analysis, I hear people say, "well, the government can tax the rich people and subsidize the insurance companies".
There is only one answer to that: There's No Such Thing as a Free Lunch
Welfare or Insurance?
People who otherwise have high IQ get really upset at this point. After all, Carl's house is gone. They feel for Carl. Somebody has to help Carl.
Caring about your fellow man is a good trait.
However, you have to remember that helping Carl after his house burned down is charity — not insurance.
Forcing insurance companies to act like charities will destroy insurance companies.
Just like forcing farmers to give food away for free will destroy the farmers, forcing bus companies to offer free rides will destroy bus companies (New York City's MTA is a good example), forcing construction workers to work for free (everybody needs a home, right?) will destroy construction workers.
If you want to help people whose homes burned down, well, there are excellent charities like the Salvation Army. Go contribute.
