The real story here is the epidemic of black violence in the United States, which is on display in cities of all sorts of sizes across the country, completely disproportional to the percentage of the population. Not only individual crimes, like murder, where a group that is about 13% of the population commits at least half (undoubtedly more) of the homicides, but the sorts of group criminal activity to which we've become accustomed. Mall mob violence. Outdoor festival mob violence. The local and sometimes national press will typically report on these sorts of common incidents and use the obligatory "teenagers" label, which then inspires about a thousand replies from the public correctly guessing that the reporters won't say "blacks." The response from apologists is that there is some sort of mass conspiracy by police, judges and "whites" to round up black people who aren't doing anything wrong and throw them in prison. The truth of the matter is that blacks are committing crimes, particularly violent crimes, at levels far, far out of proportion to their share of the total population, including far, far more than other minority groups in similar economic straits, like Hispanics.
You can't have a group where three out of every four kids are born to single mothers. That group is dead. And the percentages keep rising. One day in the not-so-distant future it will hit 90%. This is what breeds super-predators in society: angry young men. It produces young women who imitate their mothers and have children with loser men who abandon them, and the cycle continues. Majority black schools in these cities aren't schools, they're daycare/ housing facilities. Speak to any veteran urban schoolteacher about what happens in these schools. Speaking proper English and valuing education and learning is deemed "white." It's group/racial suicide, producing unhireable young people. Blacks who work their way up to lower middle class/middle class earnings leave as soon as possible. Businesses flee because of the crime and never come back. The cry from the civil rights industry and white liberals is then to have more "job training programs." I like Jack Kemp's old idea about "enterprise zones," but government won't solve the problem in this manner, either.
