I did no such thing.Poor people are a group if you are classifying by wealth alone. And they will share some characteristics, and other's will be radically different. There aren't major gang problems on reservations, and there isn't as much suicide in the inner cities. Poor people in Los Angeles live about as long as everyone else, but poor people in Tulsa have extremely low life expectancy. So it is not super helpful to point to one thing or the other.
And finding patterns, after you tease through all the interactive markers, doesn't tell you what the cause is. People don't create self destructive behavior on their own, if you can actually find something like that, you'll find it is the result of external influences.
After that, you really have a choice of addressing external factors that can influence choices, slavery, genocide or ignoring the problem. The later is in current vogue, because there is nothing people seem to hate more than feeling any sort of responsibility to their society. Makes me wonder what would happen if we needed a new Draft.
That connection was suggested as more important than the other factors that go into why it exists. I didn't do that.
Never did I say or imply that simply being black was a cause of violence.Someone brought up a metric - race. Sorry we're discussing it as a cause of violence.
