And people don't want to be in the street watching their houses burn down, they don't choose to be, and the cost of their loss is determined by the severity of the fire rather than by anything they have control over. And yet in spite of those shared characteristics, fire insurance is an excellent example of a product for which capitalism is spectacularly well fitted -- so much so that when Adam Smith was going on and on about the general deficiencies of corporations, insurance was a service he singled out as one of the exceptions; it's something the early corporations of his era were actually good at.
Except that it's absolutely not good at it at all.
Generally speaking, insurance is not very capitalist at all. It's redistribution of risk, it's one of the earliest types of communistic endeavors. Everyone shares the cost up front for an essentially unpredictable scenario with very low likelihood and very high cost.
I mean, insurance in and of itself is a very good idea... I just don't think it's something that can be considered "capitalist" in nature.
If it isn't capitalist, how did Warren Buffett make so much money selling it? It's not like his customer is the government and he's paid from taxes. No, not everyone shares the cost up front. Only those who make a bargain to have their risks covered share the cost up front. If
everyone paid and
everyone got covered whether he wanted to or not,
that would be a communistic endeavor.
It isn't sharing that makes something communist rather than capitalist. Capitalists share all the time -- it's why the portions of the capital they own and the profits they collect are called "shares". What makes something communist is
compulsory sharing.
The insurance business is a garbage disposal business, like Waste Management, Inc. Economically, risk is just another kind of garbage -- it's something people have and don't want so much that they'll pay somebody who's less averse to it to take it off their hands. Just as the widget business consists of trading a widget from people who like one less than the widget price to people who like one more than the widget price, the garbage disposal business consists of trading garbage from people who like it less than paying the disposal fee to people who like it better than losing out on the disposal fee, and the insurance business consists of trading risk from people who like it less than paying the premium to people who like it more than losing out on the premium. The economic difference between a normal widget business and a garbage/insurance business is merely the minus sign in front of the price people are willing to pay for the item being sold.
The concepts behind capitalism inherently rely on a free market system (nowadays let's settle for free-enough). It relies on market forces of supply and demand to produce an equilibrium price for the good or service being traded.
Insurance doesn't work that way. Insurance disrupts the supply-demand relationship. The supply is provided by the doctors and hospitals, not by the insurer. The demand is being provided by the consumer, not the insurer. The insurer's position as a redistributor of risk results in the actual price of supply being masked from the consumer - the consumer no longer has a clear idea of what the prices of the service are. That doesn't mean it's not a good idea - the value at risk for insurable services is waaaaaay too high for an individual to bear, even if it's incredibly unlikely. It also doesn't meant that people can't make money off of it.
I think it's also worth noting that your own analogy seems to undermine your argument. In almost every part of the US, waste management is a non-competitive business. They're almost always municipal services, even if they're outsourced to a private company. They are monopolistic, but they're generally natural monopolies, and competition wouldn't bring the costs down. They're also services that are communally necessary - we truly can't have a portion of citizens "opting out" of waste removal, because that presents a health hazard to the entire community.
I also think this is one of those areas where the technical definition of "capitalism" and the functional usage of "capitalism" cause a pretty big disconnect. The academic question of who owns the means of production has very little to do with how things function in the real world.
