From the piece:
This idea that the hillbilly’s poverty is a choice allows more upscale Americans to feel comfortable while laughing at the antics before them. It also pushes some people to embrace the stereotype as a badge of honor. “Guitars, Cadillacs, hillbilly music / It’s the only thing that keeps me hangin’ on,” Dwight Yoakam once sang. For more contemporary examples of re-appropriation, you can attend any number of Tea Party rallies. The classist term “redneck,” originally coined to indicate those who worked so hard and so long in the sun that they sported sunburns in the designated anatomical location, likewise has been adopted in the name of all that’s good and holy. What’s more American than a hard day’s work.
