Sampling royals

"Top earning Arabs and regional decision makers prefer CNN over Qatari rival Al Jazeera for their English language news, according to a new survey." I have the feeling that the sample comprised five Saudi princes. And why do I have the idea that a Lebanese crook came up with the idea of polling "top earning Arabs." I like that category, and I am sure that Karl Marx would have liked it. He should have polled the number of "top earning Arabs" who are polygamous and who own slaves. (thanks FT)
