How about plain and simple GREED. Here on Long Island, a baby is considered a speed bump in one's way to SUCCESS. It's NO conincidence that the fertility rates are in areas where the people are very religious. Talking about white fertility is probably a great way to get people to read the article, but it's really addressing a larger issue of the devaluation of children and the elimination of religion in people's lives.
I'd say your single paragraph is far superior in clarity and brevity.
