What are some examples of the nobility's contempt of the commoners?

In response to the crowd's cheering for Caesar, Brutus states n Act I, "I do believe that these applauses are/ For some new honors that have been heaped on Caesar," as if the commoners aren't intelligent enough to choose their own leader. Casca, a puppet of Cassius, called the commoners "common herd," "tag-rag people," and "rabblement." The commoners also have "stinking breath," "sweaty nightcaps," and "chopt hands." Two government tributes, Flavius and Marullus, antagonize the commoners in Act I for celebrating Caesar's return by telling the "poor men" to "Be gone!"
