America’s greatest shame in 2015 is not a piece of cloth. It’s that a black boy has a life expectancy five years shorter than a white boy. It’s that the net worth of the average black household in 2011 was $6,314, compared with $110,500 for the average white household, according to census data. It’s that almost two-thirds of black children grow up in low-income families. It’s that more than one-third of inner-city black kids suffer lead poisoning (and thus often lifelong brain impairment), mostly from old lead paint in substandard housing.
