@frauenfelder The U.S. homicide rate is 10.5-7.9 per 100,000 population vs Europe's less than 2 per 100,000. The U.S. rape is 7 times higher than the average for Europe. US robbery rates are 4 times higher than those in Europe. Also, US has the highest income inequality in the rich world and over the past 20–30 years and have also experienced the greatest increase in income inequality among rich nations. The link between wealth inequality and violence is well documented.
