Who represents the “New South” in the short story, "A Rose for Emily"?
Homer Barron represents this "New South." He is a Yankee who is the foreman of a crew of workers who are making improvements to the town. Homer, because of his "blue collar" status and because he was a Yankee, was not accepted by the older generation of citizens in Jefferson; however, the younger generation had no qualms (eNotes).
The North, before and after the Civil War, were more technologically advanced than the "Old South," and for a long time, the South resisted this change and the advancement of technology, since they were an agriculturally-based society. They realized, however, that they could not resist this change or they would never be able to support itself. The North had begun to have large factories that could mass produce goods and have them shipped via railway to other areas of the country, while the South was lagging behind in this area.
The Jefferson Board of Alderman also represent the "New South" because they try to collect taxes from Miss Emily; whereas, years before, they would have never done so because of Colonel Sartoris "old school" way of running the town.
