The paradox of US healthcare system (life expectancy)

The US spends more on health per person than any other country, yet the life expectancy of American citizens is only 78 years, far shorter than in countries with a much lower expenditure on health per capita. Remarkably, even life expectancy is in decline in the US, whereas in the rest of the world the trend is upward. The country which probably has the best rate according to Max Roser (life expectancy/health expenditure) is Japan, where life expectancy is 84 years and health expenditure is half of the US figure: $4,000 vs $8,100. The European country where citizens live the longest is Switzerland (83.9), which invests approximately $7,000 in health for each citizen. Health expenditure per capita ranges in the rest of European countries between $3,000 and $5,000, with life expectancy figures in the same range: 83.5 years in Spain, 83 in France, 82.8 in Italy, 81.4 in Germany and 81.5 in the UK. Many people link such discrepancy between life expectancy and health expenditure to higher administrative costs for the US system. Others point out that, compared with other countries, American society is more violent and that this directly affects healthcare. (Source FT)
