Social differences have changed incredibly in recent decades. The world has undergone an evolution that no one could have predicted. Aspects such as racism, social class and individual perception have changed dramatically and now represent an open-minded modern world. The multicultural push that our country and our world have experienced has brought 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 theme of social differences is the main theme of the book. The book directly addresses the main problem of racism, for example, and deals with it in a special way. Set in the 1930s, To Kill a Mockingbird takes a close look at the social differences of the time.

Students think this in school to prepare them for real society. The statements in the book are completely opposite to what we try to teach children and adolescents today.

This clearly indicates the lack of social justice in the novel. People of a race other than Caucasian in a public building have a reserved seat, a practice that would be severely denounced today. This shows the drastic contrast between the book and our everyday world. Likewise,
