Yes! You have no idea how many times I have heard this as justification for eliminating everything from food stamps to free clinics.
True! Just take a ride along older commercial “strip malls” or low-rent storefronts. What do you see? All the predatory businesses that you mention, plus Plasma Centers, Pawn Shops and “Buy Here-Pay Here” used car lots. All of these are generating huge profits by feeding on “the negative worth demographic”.
Well and truly spoken!
