Your generalizations are not borne out by the facts.
Crime, single mom families, welfare dependency,failure rates are heavily skewed minority on a per capita basis.
Some is racial (a few percentage points) but the big problem is that the nanny state has bred blacks to expect failure, to admire the gangsta ethic instead of the work ethic, and to partayyyyyy instead putting away for a rainy day.
I don't disagree with a lot of what you've pointed out, however it should be emphasized that where there are strong two-parent nuclear families involved and parental interest in their children's education, that race really doesn't matter much when it comes to achieving success.
My experience with high achieving African-American students found them to mostly be involved with their churches (in choirs, youth groups, etc.) and in school activities which promoted good citizenship (junior ROTC, etc.).
Low-achieving African-American students mostly came from large single-parent, non-involvement families where drugs and violence were often occurring. So, IMO, it had nothing whatsoever to do with race and everything to do with socio-economic class.
