The Importance of Being Earnest reveals the differences between the behavior of the upper class and that of the lower class. Members of the upper class display a great deal of pride and pretense, feeling that they are inherently entitled to their wealth and higher social position. They are so preoccupied with maintaining the status quo that they quickly squash any signs of rebellion. In this play, Wilde satirizes the arrogance and hypocrisy of the aristocracy. The lower classes in Earnest are less pretentious and more humble, but equally good at making jokes.
Although many of Wilde’s characters in Earnest are aristocrats, he ultimately parodies the upper class’s pride and pretension.
By imitating and trying to marry into the aristocracy, Jack is a hypocrite and a traitor to his own class.
