That is true, but then what is the solution? Is it to keep on subsidizing this ever-increasing group of Americans who do not have the intellectual wherewithal to contribute to society, or can we do something about these leeches?
Or more clearly stated, do we have the guts to do what's right? That would involve separation and sterilization leading to the eventual elimination of this parasite class of Americans who cost the country half of a trillion in terms of welfare, crime prevention, disease, and incompetence in jobs taken from more qualified people thanks to affirmative action/discrimination.
I should add that the cost is half a trillion annually. The real cost might be higher.
