There is a lot more to it than that. At a bare minimum, you are also paying for the office rent, the administrative cost of billing through insurance, the administrative cost of the insurer, malpractice insurance, and the price of the doctor’s education. All of these factors (except maybe rent) are higher or even unique to healthcare in the US. Capitalism isn’t even to blame for most of these. A free market would have price transparency, and would incentivize direct billing over billing through insurance due to lower overhead. Just because it’s the USA doesn’t mean it’s capitalism. That said, nationalized healthcare also seems to be able to solve some these problems through collective bargaining on drug prices, and reducing the billing overhead.
