What is the central moral or theme of the story that Chapter 47 prepares the reader for?

Chapter 47 explicitly sets the stage for the narrative that follows by stating its central moral lesson. After making a connection to the previous chapter's story about goats, the narrator urges the listeners to pay close attention. As directly stated in Chapter 47, the upcoming story is designed to illustrate a specific point. The text says to "listen now with attention to this story of how the extreme state of greed for wealth leads to a downfall." This clearly establishes that the primary theme the reader should anticipate and learn from is the destructive nature of avarice.
