Social differences have changed incredibly over the past few decades. The world has undergone developments that no one could have predicted. Aspects such as racism, class and individual perception have changed dramatically and now represent a modern, open-minded world. The multiculturalism that our country and our world have experienced has brought with it a new wave of cultural, racial and social differences. The world has changed for the better and communities and individuals are now more open to the differences of others. In To Kill a Mockingbird by Harper Lee, the subject of social differences is the main theme of the book. The book directly addresses the major problem of racism, for example, and treats it in a particular way.

When Tom Robinson and Atticus go to trial, a separate balcony is reserved for "colored" people: "The colored balcony ran along three walls of the courtroom like a veranda on the second floor..." (Lee 164). This clearly indicates the lack of social justice in the novel. People of races other than Caucasian in a public building have reserved seats, a practice that would today be severely denounced. This shows the radical contrast between the book and our everyday world. In the same way,
