White Trash
When NPR becomes so politically correct that you stop hearing about white trash, all bets are off.
I might add that as long as the expression third world is used with impunity by the mediots, their staring google-eyed, out of one side of their face, and calling our president's policy "nation-building" sounds like envy on their part--whereas they prefer colonialism, our commander-in-chief is trying to set people free.
