How are hilly and skeeter the same

Hilly Holbrooke and Skeeter (Eugenia) Phelan are characters in Kathryn Stockett's novel The Help. The main thing they have in common is their background—they both belong to wealthy, well-established Southern families. They are both young women living in Jackson, Mississippi, in 1962; they have the same social status and they (initially) belong to the same circle of friends.
However, the similarity ends there. When the novel opens, Hilly is married and has children, while Skeeter has just graduated from college. Skeeter is bothered by the relationship between the white women and their black maids ("the help") and decides to write a book exploring this relationship. This project has personal significance to Skeeter because she misses her family's maid, Constantine, who raised her when she was a child. Skeeter is very aware of the whites' and blacks' common humanity. ("I did not know there were so many laws separating us," she says about the Jim Crow laws.) Hilly, on the other hand, is the one trying to increase this separation. Not only is she racist, she also hates other white people (like Celia Foote) who do not have the same background as her.
At the end of the novel, after Skeeter's book exposes Hilly's bigotry, Skeeter and Hilly are bitter enemies.
