Uh because people blame poverty for the murder rate perhaps?
You said nearly every country has inequality exceeding that of the U.S., that's wrong even if you include the undeveloped countries.
Inequality matters as much as poverty. Inequality+poverty leads to alienation, the greatest social ill. Alienated people are the ones who kill with disregard. Poverty is just a single aspect of the causes. It matters but it's incomplete without the others.
