Three Killed as Pakistani Cartoon Protests Intensify

I'm sure someone has written about this already, but IMHO, these protests are based in somethig other than the Koran, Cartoons and Muhammed. It's the anger toward those that have more. It's anger about their living conditions and poor prospects. Not that they know what else their is, but that they know it can't be worse than what they got. Or could these lines of anger be geared toward the West regarding something else?
