How does the playwright use satire in the play, The Zoo Story?

Albee uses satire in The Zoo Story to comment on the way different social classes choose to view and ignore each other in American society; specifically, he highlights the way that in which members of the upper classes deal with members of the lower ones. This is illustrated with the character of Peter, who Albee uses as an example by having Jerry methodically bring him down to an animalistic level in order to show that he is just like everyone else.
