Burris Ewell and Walter Cunningham are both from extremely poor families. How do the boys differ ?

Like Burris Ewell, Walter Cunningham comes from a poor family, but that is where the similarities end. Walter's family is poor, but it also has values, dignity, and pride of accomplishment. Mr. Cunningham models this behavior in the way he works his land and pays his debts. He may not have money, but he pays with what he has. 

Burris' family shares none of these traits. His father is lazy, unmotivated, and prefers to cash a welfare check, as opposed to working for his money. Burris is neglected and insolent, whereas, Walter is well cared for and respectful.
