Not really. Many are scientists, entrepreneurs, politicians, journalists, etc...
They have one thing in common; that is not being religious.
Hence why all these conspiracy nuts are always portraying them as baby-eating Devil worshipers. LOL
Hmmm, a good start? The most intelligent man that ever lived: Johann Wolfgang von Goethe and more recent example is the Polish Joseph "Hieronymus" Retinger (responsible for the creation of such organizations like the NATO, the EU......and he started the Bilderberg Conference, which is nothing more than a club meeting, where important people coordinate their efforts against criminals, dictators, the Vatican, etc...; basically, they want to make sure You don't end up on the cotton fields or in gas chambers again).
What these people have in common, is that they are "grey eminences", people who are in the background.
