Isn’t part of the lack of efficiency of the US system the eye-watering prices for treatment? There seem to be all kinds of incentives for overtreating (eg, using more expensive diagnostics equipment for a simple broken bone), drug costs are unhinged, etc. It’s not only about creating a universal system but also an efficient one, and I did hear Sanders on the Joe Rogan podcast the other day mention some of these things, so maybe not all politicians are so oblivious to this?
