From a Mercury News interview with Bill Gates:

"I've said many times that if we just re-sorted the world so that you randomly lived next to the majority [and knew] how the majority of people lived, you'd say, ``Oh my God, her baby just died of malaria; my God, look at that dirty water.'' And the IQ applied to this thing would be a thousand times bigger, because whenever you describe this to people, or they go out to these areas, they come away very affected."
