The US healthcare system is an absolute hellscape, of that there is no doubt, but it's also even more bizarre than many people claim, and many of the list prices you see being posted, are not actually the prices people end up paying,
There are very strange incentives at work, where the hospital will vastly over-inflate the list price (i.e. the price the hospital quotes the insurance company ultimately paying the cost), because it gets to claim revenue from the government by claiming that a proportion of the difference between the total list price, and the actual monies collected (i.e. the true price it collects from the insurer), were used to fund "free" care for the poor.
Meanwhile, the insurer gets to claim that the difference between the pretend "list price" and the "true price", shows its ability to negotiate the price down.
So you have a double perverse incentive which leads to it being basically impossible to understand true healthcare pricing in the US.
I listened to an economics podcast recently about a straight up private healthcare provider in Kansas City, which only accepts cash and refuses to take insurance. It offers many of the services at a fraction of the mainstream US healthcare cost, their prices have not risen since the 90s (so have gone down in real terms), and their business is booming, priced cheap enough for lower middle class Americans to just directly pay for certain treatments.
The true indictment of the US healthcare system that this straight-up paid for healthcare is actually less of a nightmare than their unholy fuck up of a model!
It is genuinely, horrifyingly complex, and actually way worse than even its detractors claim. It would actually be better if it was a straight up raw capitalist private system where hospitals competed for patients.
