What were the hardships of poverty?

THe Finch family was quite poor yet relatively well off compared to most other residents of Maycomb. We see poverty in some pretty bad forms. There is both white poverty and black poverty. In chapter 2 Walter Cunningham Jr. does not have any money for lunch, that day or any other day. THe Ewells including Burris and Mayella live in the dredges of poverty, largely of Bob's own making. Tom Robinson and the blacks all live in poverty but stil, unlike the Ewells, maintain cleanliness, order and dignity.
