One new: billionaires are de-facto kings in their small domain, because companies are authoritarian, not democratic. Such concentration of power and wealth makes monumental things possible. If the Egyptian elite didn't have such concentration of power and wealth, only very small pyramids would exist. If Elon Musk only was allowed $100 million, he probably wouldn't have the most advanced and cost-effective rocket company in the world, the insanely cool Spaceship, and the goal of a Martian colony. On the other hand, few billionaires are working towards a lofty goal. Most just to make even more billions by whatever means, to put their initials in the high score board.
