From Our World in Data: "The US stands out as an outlier: the US spends far more on health than any other country, yet the life expectancy of the American population is not longer but actually shorter than in other countries that spend far less."

Why?

"[A]dministrative costs in the health sector are higher in the US than in other countries"

"[L]arge inequality in health spending…. The top 5% of spenders accounts for almost half of all health care spending in the US."
