You have it backwards. Rich neighborhoods are created by people that are honest and hard working; people that would not mug someone simply because they themselves are failures.
The Blacks that live in my neighborhood are not muggers and would be appalled by your statement.
Stay safe; stay armed.
There are delinquents in every neighborhood. Many of the kids in my neighborhood (median home price = $1.8 million) are as dishonest and lazy as those you'll find in the poorest slums. But their parents are rich, so they don't go around robbing folks for $20. I agree that culture is very important. But so is poverty.
