Wearing hand me downs and goodwill clothes? Check. One black and white TV in the house until sometime around 1990? Check. Parent working multiple jobs and long hours? Check. Cabbage and hot dog slices a common meal? Check. I'm honestly curious at what point someone is acceptably "pretty poor" in your eyes?
You're going to have to do better than that, I'm afraid. I can cross all those off my list, and we were middle class, at worst.
