The welfare system in this country pays the least employable women to have children by the most exciting, i.e., dangerous men they can find. Then we try to rescue those children by putting them in preschools with better role models than their parents. Then the women have more children.
We don’t even have to address innate differences, racial or individual. The welfare system has a dysgenic effect on populations and a socially destructive effect on the family. Better to pay welfare candidates NOT to have children than to have children.
Whites lag blacks. Where will the descendants of “white trash” as opposed to “poor whites” be in two generations? Then see what happens to low income white families as jobs disappear and welfare incentives become more acceptable and more attractive.
