Anyone here been urban, working poor?
Yeah, me. Food stamps and everything.
My parents still *never* fed me potato chips, soda, fast food, canned "prepared" foods, white bread, or any of that stuff. I never tasted any of those sorts of things until we moved out of the low-income city neighborhood that we lived in and out to the suburbs/rural part of the state with middle class families who all bought that stuff and fed it to their children.
I know one anecdote does not make anything resembling a rule or a trend or whatever, but it is certainly possible to be "urban working poor" and not shovel garbage into your children's bodies.
