You ask, "Isn't the point of insurance to spread the cost of things like that across a large pool of people so it doesn't hit anybody too hard?"
You'd think so, wouldn't you? After all, that's the theory of big numbers at work. But that's not the case here at all. Anything but. If we wanted to spread the risk over the largest possible pool, we'd have a single-player system that includes all 300 million plus Americans.
Since we don't, you can make certain inferences, starting with the fact that medical insurance has nothing whatsoever to do with health care except in the twisted minds of Chicago School libertarian fanatics and free market pitchmen.
We're not really talking about medical insurance anyway; it's protection money paid to an organized crime syndicate to keep medical providers from stealing your house, cars, bank accounts and anything else that isn't bolted down in case something serious (i.e., expensive and maybe requiring hospitalization) happens to you.
And how do we allow such an unfair, destructive system to interfere in our lives when all other industrialized countries do much better? After all, their systems produce better quality-of-life statistics and superior treatment outcomes at far lower per capita costs. So why do we put up with this bullshit system? Simple. We're idiots.
The US is unique in the world in its child-like belief in corporate good citizenship and the intrinsic benevolence of a medical system based solely on profits. This is not only naive and dumb as dirt, it can't happen under US law and SEC regulations that demand a publicly owned, for-profit corporation base its entire business model on achieving one single objective: maximizing shareholder equity.
So anything that bumps the stock price is good, and anything that lowers it is bad. Paying claims is bad because it sucks money from the bottom line, while denying claims is great because it saves money that contributes to corporate profitability, which ultimately helps raise the price of the stock, keeps the investors happy and keeps the SEC off the CFO's back for another quarter.
In short, it's literally impossible for a US for-profit publicly held medical insurer to live up to its opposing obligations to both its subscribers and shareholders at the same time. And, as noted above, if somebody has to get screwed, by law it's going to be the peasants.
And that's the short version of how the profit motive combines with lack of corporate accountability, an insupportable belief in intrinsic corporate goodness, a culturally ingrained resistance to anything that wingnut demagogues can label as "socialist," and a corollary trust in market solutions to social problems -- despite the fact that the only problems typically addressed are the temporary cash flow problems the solution's pitch men may be experiencing -- to produce the most expensive, least accessible, most elitist and most inefficient medical system in the entire industrialized world. And in quite a few countries that can't make any claims to industrialization, as well.
Here's a
recent chart updating the World Health Organization's landmark 2000 comparative study of 190 countries' medical systems. Note that, at 37th, the US ranks behind all EU countries, UK countries and a bunch of others who just do a better job of taking care of their citizens' medical needs.
And that's the bottom line, unfortunately. In the US, any connection between medical insurance and good health care is purely accidental.
