Yes, parallel is the way to describe it. Not driven by racial animosity, I don't think, but just people keeping within their own circles (kind of like Jews and Asians in New York).

The interest in professional services makes sense when you consider that Delta, UPS, Home Depot, etc, are headquartered there. Logistics services, consulting, legal services, etc, are all in high demand, and the city is the hub for that sort of work for the surrounding region.
