My rural experience (UK) may be different from what you're expecting if you're taking an americentric viewpoint. I had one neglectful parent who later married physically abusive step-parent. I experienced physical violence and sexual abuse as a child, but my surroundings outside of the home were largely positive despite poverty.

EDIT: also some of your claims here are questionable. I don't believe that children in an average poor household experience abuse + drug usage. I knew plenty of poor children who had one parent, I knew some who had a drug user in the house and I definitely knew some who were abused but I didn't know a single person who ticked all of those boxes.
