National health care provides better care for the majority in other industrialized countries, which is why they have better average stats. (Average stats mostly measure the majority.) The US system provides better care for the rich, partly accounting for the
20 year difference in longevity between the rich and poor in the US. The rich from around the world come here for super deluxe care.
Service inflation is way beyond the CPI, and health care is labor intensive. The CPI mostly measures machine made goods, subjective adjustments for quality, and the imaginary rent that homeowners don't pay themselves (homeowner's equivalent rent).
