Significance of ending of The Hamlet

Final segment of Faulkner's The Hamlet involve three guys - Ratliff the central narrative figure, Henry (the guy who bought the horse and broke his leg - and his wife tried unsuccessfully to get the $ back from Flem Snopes) and a 3rd character on whom I never got a reading, Bookright - Henry became aware the Snopes was spending his nights diging holes on the grounds of the old Varner estate, formerly the mansion owned by the patriarch of Frenchman's Bend in the antebellum era - in other words the now near ruined house has passed from feudal colonial to old south to new south - the 3 men spy on Snopes at night and realize he's digging for treasure hidden against marauding bands during the Civil War. They come back later at night with an old douser who uses a split peach-tree branch to find where the treasure is buried and the 3 spend the rest of the night unearthing bags of silver coins - but of course they're already fighting w/ one another about dividing the wealth. This echoes back to many literary antecedents - as far back at least as Chaucer - I think it was the Pardoner's Tale? - which led to the simplistic moral conclusion that $ is the root of all evil. Faulkner's vision is a little darker and more comprehensive: he's showing I think the gradual degradation of not only money, commerce, wealth but of the social values that hold a community together or split it apart over many generations - not that he's romanticizing the past a la Margaret Mitchell but that he sees an inevitable baseness and cruelty as the society becomes more fluid and more competitive and even, to a very small degree, more open.
