A single line from this column by Joel Miller at RazorMouth put me in mind of something Hans-Herman Hoppe wrote in Democracy, the God that Failed regarding the tendency of democracies to devolve to the lowest common denominator.
Miller posits that the degeneration of the language is both a symptom and a cause of social and moral decay. (Or maybe I'm reading my own beliefs into his words.) Though I would seldom dare to contradict Sir Winston Churchill, democracy really is the worst form of government imaginable. The "ghetto-isation" of the language dramatically illustrates that thesis.
