Well, man, that's because it is clearly presenting people with higher education and very white in appearance and culture as the people who should be breeding, and people with worse education and cultural identification and behavior that's more common with not so white people in the US as those that are doing too much breeding. In reality education level has more to do with your parents zipcode when you were born rather than your DNA, and cultural behavior isn't any part of human DNA or a thing you breed for. Sorry about all your feelings, you seem to have missed that I was defending the film for being a comedy and that these opening bits are jokes not a serious attempt at understanding or addressing problems.
