Just cause one group does better than another is not proof that systemic issues don't exist for another group. In the article they cite multiple sources of anti-black resentment being the cause of D.C. not receiving statehood, I only cited the letter because it was small and to the point.
It was a part of the cause, I've already ceded that point to another commenter. I did research and yes, many decades ago there were racial prejudices involved. There's nothing to indicate that that's still the primary motivator to keep DC a district and stating such is baseless speculation.
