Other hypotheses have greater explanatory power: excessive poverty, both actual and relative, and excessive affluence.
Excessive poverty is probably more prevalent in the U. S. than in any of the countries that have a better infant mortality rate and female life expectancy at birth. This is probably true also for all but four or five of the countries with a longer male life expectancy. In the notably poor counties that exceed us in male survival, difficult living conditions are a more accepted way
