I'm not sure what point these folks are trying to make with this piece (note: it's unsigned!) unless it is that poverty and lack of education are hereditary and we must, at all costs, keep this out of the American gene pool.

Note - I especially like the image of the happy, safe, affluent, suburban white people that they use to frame the story. Very subtle!
