No not true.
The black...and white.... slum slut out of control welfare queen and the semen spewing baby-daddies were not a historical norm.
The impoverished stupids have always been on the higher end of the incarceration numbers however the rails that demanded decent behaviors have been removed and monetary rewards never cease.
I would offer semen spewing baby daddies a cash payment of $1000 for every year under 35 that they get a vasectomy such that a 18 year old would get $17000 and a 19 year old would only get $16000 and so on. After 35 maybe a fixed sum.
