In this superb article by Heather Mac Donald the intersection of the three is examined after the horrible shootings in the black church in Charleston.

An excerpt.

New York Times columnist Nicholas Kristof anticipated Obama’s speech with his own leap from the shootings into liberal bromides. America’s greatest shame in 2015 is not the persistence of the Confederate flag in the South, Kristof wrote, but the fact that “almost two-thirds of black children grow up in low-income families.” Kristof saw this statistic as a manifestation of racism: “The larger national disgrace,” he said, is that “so many children still don’t have an equal shot at life because of the color of their skin.”

Skin color has nothing to do with it. The overwhelming reason why children grow up in poverty “in 2015” is that they are being raised by single parents. Children with no father at home are between four and five times more likely to be poor as the children of married parents, whether they are black or white. But with 72 percent of black children born to single mothers — nearly three times the white out-of-wedlock birthrate — blacks’ higher poverty level is inevitable.

The formula for escaping poverty as an adult also has nothing to do with race: Graduate from high school, wait until you are married to have children, and work full-time. Whites who eschew those bourgeois behaviors are as likely to be poor as blacks who eschew them. Only 2 percent of individuals who follow those rules are in poverty, according to Isabel Sawhill of the Brookings Institution; 72 percent of those who follow them earn at least $55,000 a year. The American poverty rate would be cut by 70 percent if the same percentage of Americans engaged in those responsible behaviors as did in 1970, regardless of race.

America spends over $1 trillion a year on programs for disadvantaged families, estimates Ron Haskins of the Brookings Institution. In the liberal worldview, where compassion is measured by government spending, that vast sum should buy the American “we” some dispensation from race-mongering. Compassionate or not, however, that spending is unable to counteract the effects of nonmarital childbearing, a social catastrophe about which Obama, Kristof, and other scourges of alleged racism are silent. Family breakdown explains the other racial inequalities that Obama seized on. He criticized “us” for “permitting” so many children to grow up “without prospects for a job or a career.” This lachrymose accusation again overlooks the reality that a black boy who graduates from high school today with a modestly respectable GPA will have scores of selective colleges beating down his door; should he finish college in decent standing he will be able to write his ticket to the graduate school of his choice. If few black students are able to take advantage of those racial preferences, it is because children from single-mother homes enter school far behind their peers in reading, math, and social-emotional skills, a gap which schools struggle to close. Fatherless children, especially boys, are less likely to graduate from high school or college and are more prone to crime and gang involvement.
