I don't doubt it. Check somewhere like Bryson City North Carolina. That place is so removed from mainstream America, I guess that is what they mean in saying Appalachia. My heart really went out to the people, poor white folks like I'd hardly ever seen before.
And yet, people made jokes about hillbillies but these folks really are against it in ways.
Christian love has to help out everyone, to the best of our abilities, of course, one should be caring for those in their own house, own backyard, own environs first is what I think.
And just because I don't see that same kind of poverty wherever else, doesn't mean it doesn't exist.
