True, but unfortunately the whites are as unsuccessful as blacks (in different ways, but with the same outcome: a shrinking population). Besides a new bank commercial with two lesbos (one the responsible one, the other the carefree spender), have you noticed the commercials selling Halloween costumes for pets? Those are for white people, who are going the way of the dodo; the few I know having children are doing it for the same reason as urban blacks (for freebies) - no marriage (or even long-term relationships), just “gibsmedat”...
Fortunately, I am almost completely unexposed to commercials ... although I do see the pet costumes when I’m at Petsmart getting crickets for our lizards.
Your examples are, in a way, encouraging, in that they demonstrate that biology is not the real issue. Behavior is the issue, and behavior can be significantly affected by changing incentives.
