It means they are perceived to be very good at something. I, personally, would say that only one of them is. However, I do not recall many complaining letters to Mudcat about the fortunes amassed by Conrad Black, Robert Maxwell, Jonathon Aitken, Duncan Sands and other more anonymous contemporaries of their ilk. That tells me a lot more about our society and its "values". For some reason, it seems less respectable for one of the oiks to amass a fortune.
