Not really comparable. Rednecks vs. elitists is a difference of class and really has nothing to do with being white.
“Ghetto” vs. affluent is absolutely about what it means to be “black”. The affluent look down upon the ghetto ones because the ghettos are still playing the victim card, demanding that affirmative action remain in place. The ghetto types toss the famous Uncle Tom label at the affluent blacks, viewing them as a sort of sellout and a threat to their victim mentality of permanent handouts.
The term ‘redneck’ has everything to do with being white. (though hubby and I have fun teasing a friend of ours for being a “Mexican redneck.”
I take exception to your “rednecks versus elitist” characterization. Its more like intelligent, productive, educated white people versus low IQ, slovenly, filthy, inbred ignorant white people.
