From the book To Kill a Mockingbird, explain the social differences exposed through the students at school. What does Burris Ewell represent?

Miss Caroline singles out Walter Cunningham, Jr. when she notices he has no lunch nor any lunch money. Scout informs Miss Caroline that he and his family are too proud to accept handouts. This is why Walter repeatedly refuses to take money from Miss Caroline. Scout also mentions that he has no shoes. Walter is clearly from a poor family. We will later see how Aunt Alexandra, for example, treats the poorer families, like Walter's,...

Miss Caroline singles out Walter Cunningham, Jr. when she notices he has no lunch nor any lunch money. Scout informs Miss Caroline that he and his family are too proud to accept handouts. This is why Walter repeatedly refuses to take money from Miss Caroline. Scout also mentions that he has no shoes. Walter is clearly from a poor family. We will later see how Aunt Alexandra, for example, treats the poorer families, like Walter's, with condescension. Atticus treats Walter and his father as well as anyone else and this is why he allows Walter Sr. to pay for his legal services with goods rather than money. Walter is from a poor but respectable family. 

Burris is from an even poorer family. He is covered in filth and is ignorant. Walter's father works, but Burris's father, Bob, can not hold down a job. The Ewells live off of relief checks, a form of welfare. The authorities allow the Burris children to miss school because they've given up trying to reason with the unreasonable Bob Ewell. There are some who are sympathetic to the Ewell children but the Ewell family in general is seen by many to be a leech of the town.

Burris is ignorant and rude but he is a product of an abusive, ignorant father. Scout has the advantage of being from a family with more income but she also has the advantage of having an intelligent, thoughtful father. Given these descriptions, there does seem to be a connection between economics and education. On this sliding scale, Burris is at the bottom and Scout is at the top. She is more thoughtful and more intelligent, and this is largely a result of her family's economic and educational advantages.
