Spending on U.S. health care is out of control, expanding steadily from 5% of GDP in 1960 to 18% in 2018. There are, however, ways to curb the explosion in costs from both the demand and the supply side.

Health care costs per capita in the U.S. are almost double those of other developed countries, but life expectancy is lower than many, even South Korea, according to the CIA and Eurostat. Without restraint, costs will accelerate as more and more postwar babies age. The nonpartisan Congressional Budget Office projects Medicare spending alone will leap from 3% of GDP to 8% by 2090.
