A recent ECB paper by Ferrero et al (2017) on the effects of demographics on interest rates, contained an interesting chart that showed the life expectancy of several countries. And the USA is not doing well.
The paper is mainly about the effects of adverse demographic developments on the LT natural interest rate in the euro area. However, the more interesting part for me was this graph on life expectancy:
One can see that life expectancy in the United States has stagnated, while euro area countries still see a strong growth in the lifespan of their citizens. Quite strange that a citizen of the country with the highest income per capita in the world is living 5 years shorter on average than an Italian.
