I am having a lot of trouble finding two texts that deal with the same subject, and were written in different times. Your help would be much appreciated.
The Uncle Remus tales by Joel Chandler Harris are satirical as the smart Brer Rabbit is the Negro while Brer Fox represents the slave owners. Time after time, Brer Rabbit saves his life through his clever manipulation of Brer Fox. Harris's work is not merely an amusing tale for children; it is a clever satiric allegory.
One very satiric film on the subject of the media is Network; perhaps, this movie is based upon a written work, that you can locate.
Personally, my favorite satire is "A Modest Proposal" by Jonathan Swift. His pamphlet focuses on several problems: increasing population, mistreatment of the Irish by the British, oppression of the poor, and many others. Because it encompasses more than one subject, it can easily be matched with a satirical piece from another time period. It can be paired with Tertullian's "Apology" which looks at the oppression of one group by the ruling class. For a more modern comparison, you might want to check some of the satirical political publications. For instance, the Colbert Report has referenced "A Modest Proposal." Websites like "The Onion" have run satirical stories very similar to "A Modest Proposal".
