Black Harvard professor, Henry Louis Gates, Jr. gets arrested for breaking-and-entering his own house. In this article he goes through the details of the whole ordeal, and I think captures an important concept well at the end:

I thought the whole idea that America was post-racial and post-black was laughable from the beginning. There is no more important event in the history of black people in America than the election of Barack Obama. I cried when he was elected, and I cried at his inauguration, but that does not change the percentage of black men in prison, the percentage of black men harassed by racial profiling. It does not change the number of black children living near the poverty line. Which is almost a similar percentage as were under poverty when Martin Luther King was assassinated.

There haven't been fundamental structural changes in America. There's been a very important symbolic change and that is the election of Barack Obama. But the only black people who truly live in a post-racial world in America all live in a very nice house on 1600 Pennsylvania Avenue.
