Nope. You'll find them in most any poor rural area.
All of the ancestors on my fathers side were quite poor. I don't think any of them would have liked handouts.
There's a difference between poor rural people, rednecks, and welfare bums. A poor rural type has more taste than a redneck and is less hillbilly-ish. A real hillbilly doesn't accept welfare, they have to much pride. The bums are the decendants of hillbillys. They live off welfare.
