Is AAA auto insurance? Not exactly. I have no problem with medical insurance as long as it is actual insurance.
It is not impossible to negotiate for emergency care, it is possible to do so before the emergency. This is what insurance companies are for, if people actually bought insurance themselves they could negotiate as to which ER to go to and how much to pay beforehand.
In a free market healthcare system there would be nothing stopping either the government or private charities to pay for homeless people with stab wounds.
Since it is in the public’s best interest as well as the individuals best interest and insurance company’s best interest, there is no reason to suppose that private markets could not supply as many or more vaccines.
Information Asymmetries are are part of many markets. As you point out the classic textbook example of market breakdown caused by information asymetry is the used car market. Yet more than 3 million used cars are sold in the US each month. This is because there are markets for information and it turns out that the information asymmetries are not as big as theorized. There is lots of good information about health care and what works and does not work.You don’t need to become an expert you just need to be able to get information from one.
You can’t negotiate your price for dinner either, you either pay the price or starve in the street. That makes as much sense as what you say for chemotherapy. As long as there is a competitor down the street offering less then the price will go down. No every shopper needs to have the same marginal price for competition to work. As long as there are price sensitive shoppers then price competition will happen.
As long as you shield consumers from the price of their choices there is no way to get prices down. As long as prices go up fewer poor people will be able to afford healthcare. Government shielding people from prices is causing the problem it is trying to solve.
Not auto insurance (they sell that separately) but certainly it can be considered as towing insurance. Which is the example you gave.
People can always buy insurance themselves - but it is more expensive by yourself than if bought with others. And you had better negotiate with a whole bunch of ERs, since if your emergency happens away from your preferred one you are SOL. Which, as you say, is what insurance companies do and what we can’t do as individuals.
The more people in your pool the better you can predict costs, which allows you to make money with a smaller mark-up to cover unexpected spikes in costs. Bigger is more competitive.
Yet companies are making money providing background information on cars, and the standard advice is to bring a used car to an independent mechanic. So there is information asymmetry, but also ways of working around it.
Since when has government prevented medical providers from publishing prices? Government has finally started publishing comparative prices for a small subset of procedures, which is going to help, but why would providers publish prices in a free market, when you can attract customers with great doctors and the promise that they will live to walk out the door? I hear dozens of medical ads and none talk about price. And they are clearer going after patients not locked in by their insurance company.
Since the OP hasn’t returned to clarify the situation, I have to agree with this interpretation.
So, a lot more people would die a lot younger, and there would be some benefits. For instance, probably lower unemployment because of a smaller labor pool. Possibly lower real estate prices. Almost certainly, fewer cranky old people annoying me. However, I am now about the right age to be a cranky old person, so I’ll keep my insurance, thank you, and get off my lawn!
FWIW - my rheumatologist stopped taking insurance about 9 years ago. He was able to lay off the two full-time people he need to process insurance claims and lower his rates, which have not changed since.
