Generational poverty culture (thanks to liberals) is the more likely culprit than genetics.
Environment is also a factor. Its not the determining factor but it is a factor.
My little town has 1 black family and they’re good people. The patriarch is from Detroit. When he was a kid his father packed up the family and fled during the riots. He grew up in the hood in Jackson but moved to our tiny rural town to give his kids a fighting chance.
They’re more mannerly and polite than most of the white kids around here.
What about all the groups that have spent centuries in poverty? How do you explain that?
