Healthcare is rarely a good example of the free market. Medical decisions aren’t made by comparing costs between providers. And if you’re in rural America, you’re lucky if you have any provider. Price transparency would be nice, but maybe not as helpful as you’d like. Let’s say you’re in the middle of a rural area and the ER says you need stitches — but they cost $6000. What are you going to do about it? Are you really in a position to negotiate? Your choices might just be 1) get the treatment, or 2) go without.
Many things in rural areas cost more than they should. Usually on this forum we talk about the high cost of internet access and the lack of options, but medical is very similar in that regard. Services are hard to find, providers are covering a very large geographic area, and many costs are higher.
It’s not a good example of how a well functioning free market would work.
