This isn't counter to your points, more pontificating.
I am left to wonder just how much of the modern problems with and from black people is do to the focus on college.
Here are some 'hate facts'
1: Black people are, on average, lower IQ than Whites or Asians. The difference isn't massive, hell often times its trivial, but it is existent. This makes getting into higher learning harder.
2: Blacks are, on average, more physically robust than white people or asians. Again, the difference isn't massive but it does lean more towards the physical labor.
3: There are -good- elements to black culture, a strong focus on faith, family (The fatherless issue is one caused more by external than internal factors), brotherly bonds, and community.
If not for the focus on college, I could see black people entering the more physically demanding jobs or those that require more technical rather than book knowledge (Plumbers, etc). These blue collar jobs tend to be fairly well paying, and would allow black people to make up a very strong backbone of middle class workers whose natural aptitudes lend credence towards those jobs. Entire families, working together in a large community of those workers. Its ideal for them.
But instead, they are forced towards college where they will not excel. In fact, they have been forced towards it since the civil rights era, where suddenly black people specifically were pushed towards higher learning.
I think it says something that, prior to this push, black people occupied exactly the kind of jobs I mention above. We had other issues which needed solving, but black people had found an economic and societal niche which not only did they fit in, they excelled in.
Mix in other polices, absolutely wrecked welfare and 'gibs' programs which made them reliant on the state to only name a couple, and you have a people who have been pushed away from what they'd do well at, and instead have slowly stagnated and rotted.
