You reference one report, way back in 2000, that may have had some data errors. All the the health organizations that have compared the world's health care system, year after year, come up with the same conclusion, that UHC provides better health outcomes for lower cost. That is why you don't see countries that have switched to UHC wanting to switch back to private health care systems.
What fault have you found with all the reports since 2000, like the Commonwealth Fund's report I referenced above?
What world health organizations can you reference that have studies that show that our private health care system has better outcomes???
