It is a foggy window located in the soul through experiences gained that sees prejudice. It not only influences and revolutionizes sight, but also influences thought and actions. Everyone is given the opportunity to look out the window, but not everyone can see beyond the fog. The fog can be a mix of race, gender, beliefs, or behaviors. The main themes of Harper Lee's To Kill a Mockingbird relate to presumptions and prejudices; the rich rejecting the poor because of their economic standard of living during the Great Depression, the whites discriminating against the blacks, and the innocent people gossiping, which results in a weak foundation and an unpleasant relationship in Maycomb society which makes so that underdeveloped individuals live in an unsafe environment. The Great Depression caused the poor to become poorer while the rich were not affected as much. Some rich people, like Aunt Alexandra, misunderstood people because of their economic life. His different point of view emerges clearly when he rejects Walter Cunningham, a poor boy, saying: “...they are good people. But they're not our kind of people" (Lee 224). Aunt Alexandra, believing that the Cunninghams are below the Finches' economic level, ignores Scout's friendship aspect towards Walter who detests him "because he's rubbish ” (Lee 224). She is oblivious to the Cunninghams' hard work to repay Atticus “the only way [they could]” (Lee 21 has negative results on Walter making him dislike being a Cunningham, on Scout diminishing). his relationships with his classmates and friends, and about Maycomb developing an unsafe society for country people who leave because they have to deal with unnecessary factors such as money to avoid the rich prejudices Maycomb is known guilty for its racist atmosphere where blacks are inferior to whites However, not all of the white community discriminated against blacks For example, Atticus defends Tom Robinson regardless of Mrs. Dubose's hurtful words that Atticus is "no better than Negroes and the rubbish he works for!". (Lee 102) It is obvious that Atticus is one of Maycomb's most trustworthy and honorable citizens. Mrs. Dubose's assessment of Atticus has negative results on the other neighbors and clearly hurts Calpurnia's feelings. An example of this racial prejudice is found in Scout's words that “[Tom is] just a nigger” (Lee 199). Scout's words are evidence that society is unsafe for children's development. Another example is found as Aunt Alexandra convinces Atticus to fire Calpurnia, although Atticus tells her that "Calpurnia won't go away." this house until she wants it" (Lee 137).
