I would like to see him run a hospital and maybe put a dent into the problem of the $200 aspirin.
While it is true that the US health system excels along certain narrow metrics (it's particularly well optimised for providing cutting edge care to the affluent) it is poorly optimised for serving the needs of the median citizen. And it's a dumpster fire when it comes to distribution and affordability.
The solution exists, and that's to stop doing the broken thing.
