That was pretty much the entire joke behind both Green Acres and the Beverly Hillbillies, to show the difference of cultures in America in an absurd way. Seeing everything become homogeneous is kind of sad
Sort of...Green Acres seemed more to exploit that difference to create an absurd environment in general. (Filmways had a lot of trained farm animals around anyway.) The recurring joke was that Eddie Albert had an idyllic vision of being a lawyer retiring to farm life, and all of the objectively insane things people there did made perfect sense to everyone except him, including Eva Gabor.
