[The] pope is a member of the superclass, as is Osama bin Laden, who can undoubtedly claim influence over current international affairs, even if he sometimes lives in a cave. The Russian illegal arms dealer Viktor "Merchant of Death" Bout is a member, as are Rupert Murdoch and Bill Clinton...
Yeah, well... This could be said of powerful people at any time in history. Is it enough to draw up a list and call them a superclass? I'd actually be more interested in analysis of the money, the control over economic globalisation, and how economic globalisation fills their pockets and gives them specifically different or new powers. But perhaps that's in the book...
(PS Viktor Bout was arrested last week.)
Aomw thoughts of mine in that direction are here, here and here.
