I don't know any mega-rich but from what I've read, the goal is the acquisition of wealth more than the money itself. They have far more than they will ever use but that's beside the point, it's like a Johnson's on a massive scale. Same goes when they start competing with donations.
I guess if you substitute something that they can compete against with each rabroad
her that's exclusive to the mega-rich, while still leaving them enough to do whatever they want with (Brabroad
h very hard to determine), than I don't think they will complain.
