THAT is WHY they aren't assimilating. I was just talking with my kids about that. Back in the day the black families stayed together, strong family values, church-going, etc. When the “Great Society” took hold the statistics started going south, and just get worse every year. (Something like 70% with no dad). If someone is willing to reward poor behavior like getting freebies if you have another child and don't have a husband, that behavior will continue.
It is really sad to see what the democrats have done.
I agree; a black sharecropper in the South in 1920 was more assimilated/American than these rejects...
