The United States spends more on health care than any other country, with too little in the way of results to show for it. The U.S. ranks 25th in maternal mortality, 26th in life expectancy, 28th in low birth weight for infants and 31st in infant mortality. Compared to countries with better health outcomes, the U.S. spends far less on social services. This results in more ill health and requires the health-care system to provide social services that should be available elsewhere. Five percent of Americans account for 50 percent of all health-care spending. These are often poor people who are locked into bad habits in bad environments (Ezra Klein’s Washington Post blog, September 19).
