This misses an important point. Cities like Chicago and Miami compete globally, against places like Berlin and Sao Paulo. Smaller regional centers, like Oklahoma city, and Des Moines are ruled by their own elite and are not concerned by international affairs.
The wealthy in smaller regional centers don't have the ear of the Federal government, but they do employ most people in the local area, so locals are tied to their success. Locals also rely on them for donations to local hospitals, charities, and sporting clubs.
