Where in To Kill a Mockingbird is the proof that the Finches are poor?
I'm looking for the quote, something along the lines of 'Are we poor?' 'Yes' between Atticus and the kids, but I have looked, and my teacher has looked, it just seems to be elluding us.
The quote you are looking for is in chapter 2. It comes as a flashback just after Scout's embarrassment on her first day of school when she tries to explain why Walter Cunningham cannot take lunch money from Miss Caroline. Atticus' lesson on "entailments" is actually a great passage showing an historical view of those times in America's history. A modern audience would expect the Finch's to be comfortable, if not wealthy. For one thing, Atticus is an educated attorney. For another thing, his family owns land. As exposition in the story, this short scene gives personal insight into what life was like in the south after the stock market crash. It is interesting to see Atticus' pragmatic comparison of two families who otherwise belong to completely separate socio-economic groups.
