We do not live in a post-racial society. It would be nice if that were true. Here are some other things that "hold black culture back."

Subprime mortgage rates are nearly double for black and hispanic households: http://www.epi.org/economic_snapshots/entry/webfeatures_snap...

Black males are 10 times more likely to be incarcerated for drug offences than whites: http://www.hrw.org/sites/default/files/reports/us0309web_1.p...

Black sounding names are less likely to get a callback, despite identical resumes: http://www.cbsnews.com/stories/2003/09/29/national/main57568...

This is not an issue that is solved by a single election, or by making it sound like a "moral" failure on the part of blacks or whites. It is complex, systemic, and we all have our internal biases that are difficult to recognize, let alone root out.
