I live in Arkansas (you may remember us as the state that threw a fit over desegregation roughly a Jesus-lifetime ago), in a region that is pretty economically strong but still has distinct socioeconomic classes. I'm pretty confident that this post describes reality pretty well, based on 1, my direct observations as a student, 2, what I've heard from other students, past and present, and 3, what I've heard from teachers and principles, retired and practicing.

[edit] To be more clear, I think there's almost certainly a county or several in the United States where the article could apply, but not necessarily a majority. Whether or not the OP is being completely honest, on the other hand, I don't know (the username seems designed with emotional impact in mind, which is rarely a good sign).[/edit]
