In "The Breakfast Club", what concept is illustrated when Andrew (Jock) tells Bender (Criminal), the following: "You know, Bender, you don't even count. If you disappeared forever it wouldn't make any difference."?

The concept illustrated is prejudice.

Explanation:

Prejudice refers to a negative opinion of an individual or collective, without real previous knowledge and usually bordering on racism. It is often based on previous customs and traditions about a certain group.

These opinions generally generate a hostile attitude towards the individual or collective and they are usually based on stereotypes.

One of the main concepts presented throughout the film is the stereotype of each character who belongs to a certain group. As Brian's essay states at the beginning of the film, we have a jock, a princess, a criminal, a basket case and a nerd.

Since these students don't interact with people outside of their circle, their idea of each other is based on stereotypes and thus develops into prejudice against them.

Andrew thinks Bender is beneath him, implying that "he doesn't even count" and if he disappeared it wouldn't make a difference since he is a criminal. He is being prejudicial against Bender.
