Possible meaning of The Peasants section of The Hamlet

The last section of Faulkner's The Hamlet - The Peasants - begins in high-comic fashion as "a stranger comes to town" - in this case a Texan named Buck, brought in by the conniving Flem Snopes along with a herd of wild Texas ponies that he plans to put up for auction. Of course you can see that nobody in their right mind would buy any one of these untamed horses - but the genius of the story, or perhaps of Buck, is that he does manage to sell them all - starts by giving one away ends up selling the lot to the townsfolk - which suggests their complete gullibility - and includes one strand of pathos, as an obviously impoverished man comes up and insists on bidding on one of the horses, as his wife protests, begs Buck to not sell him a horse, they have no money to feed the "chaps" back home. The scene eventually becomes wild as the men at the end of the days, remorseful as if at the conclusion of a drunken debauch, try to grab the horses each has bought - the herd breaks loose, creates havoc in the town, seriously injuring at least one man - the guy who shouldn't have bid at all. So this part of the novel - the most straightforward of all in its narration and the plainest in style - is some kind of allegory or analogue - people falling prey to false prophets and victims of their own greed - it's like the banking crisis of the 21st century played out in miniature (interestingly, the young boy who witnesses the whole debacle and comes out miraculously unscathed is named Wallstreet Panic).
