I remember "Justified" portraying the area (technically it's Harlan County in Eastern Kentucky) much like you describe, and then the show visited the black portions of the region and the poverty appeared even deeper. That said, as a resident of Texas, I can tell you that that sort of poverty isn't limited to Appalachia.
