The original idea behind insurance was to provide financial protection for infrequent, but catastrophic and unexpected events that a reasonable and prudent person could not expect to be able to pay, such as dying young, major damage to or destruction of a house or building, injury to others in an automobile accident, loss of an entire merchant ship and cargo… and similar events.
Insurance started out essentially as a form of mutual risk sharing for events that didn’t happen that often but which, when they did, could devastate an individual or a business. At that time, people were (theoretically) supposed to save for smaller adverse “rainy day” occurrences.
Yet now, rainy-day-savings seem to have vanished, replaced by what seems like insurance for everything. Not only do we have health insurance (which has become a necessity, given the high cost of medical care), but dental insurance, and nursing home insurance. The latest insurance bombarding the media is car repair insurance, but there’s now also appliance repair and replacement insurance, as well as pet insurance (possibly because veterinary medical costs have also skyrocketed). That doesn’t include roughly twenty other types of insurance, such as boat or ATV insurance and identity protection insurance and personal liability coverage.
The fact that so many types of coverage exist might just go hand in hand with the fact that the U.S. has a surfeit of attorneys, but the attorneys could easily counter with the fact that Americans tend to argue over everything.
Add to that the technological and legal complexity of our modern world and the increasing costs of everything, and the failure of working-class wages to keep up with the cost of living… and, unfortunately, because people have trouble in making ends meet in paying for the basics, insurance for everything becomes the default, because few Americans can save enough to pay for all possible adverse eventualities, particularly in a litigious society.
