True, but too simplistic a story. "Billionaire" (when not inherited) generally requires EQ more than it does IQ. And a somewhat sociopathic obsession with attaining extreme wealth certainly helps.<p>Also - both the beliefs of billionaires, and social belief about them are very much shaped by human nature. Kings getting inflated self-images from the flattery of competing hangers-on was an old trope back when Rome was still a one-horse town.
