If it’s an issue of poverty then you’d expect to see poverty predict homicide rates. Yet it doesn’t. But what does? Racial makeup.
If your claim were true, white people would not just commit the majority of homicides, black people would only commit 26% of of homicides (the % of black people on food stamps), instead they double that rate.
What do you find when you look at the data? You find the blacker the state, not the more improvised the state, the more likely it is to have high homicide.
Examples: DC, MS, Louisiana are top 3 in homicides per capita and top 3 in black population as a %.
West Virginia is 3rd lowest in GDP per capita, Idaho is 4th lowest, WV is 23rd in homicide rate, Idaho is 49th (out of 51 because I’m counting DC). KY is 7th lowest in GDP yet 19th in homicide, Maine is 8th lowest in GDP yet Maine is 50th in homicide rates, Montana is 9th lowest in GDP yet 31st in homicide rates.
The poverty=crime (especially violent crime) argument does not hold water. The homicide issue in this country is clearly not a problem of poverty.
Edit: that’s 6 of the ten poorest states and the highest any of them rank is 19th, with two of them being in the bottom 3 in terms of lowest homicide
