I'll posit single-payer is much closer to a true fix than you give credit for. A significant fraction of the additional cost in the US is due to all the administrative overhead that comes with negotiating prices with thousands of insurance providers, as well as dealing with not only primary insurance, but secondary, tertiary, and sometimes even quaternary insurance providers for any given patient. And, as mentioned elsewhere, it gets multiplexed over each doctor involved in your care, since each may work with a unique subset of insurance providers.
