If you believe that health care is a public good to be guaranteed by the state then a single-payer system is the next best alternative. Unfortunately it is fiscally unsustainable without rationing.
People spending more of their own money on routine health care would make the system more competitive and transparent and restore the confidence between the patients and the doctors without government rationing.
To play safe I prefer to accept only one type of power: the power of art over trash the triumph of magic over the brute.
