Rockefeller and Carnegie were, as examples of social-engineering philanthropy, unique. They alone had such resources and will. Now you have legions of people who have to give away vastly larger amounts than Rockefeller or Carnegie had at their disposal, or might even have imagined. “Except that it’s actually hard to give away this kind of wealth, without the always accompanied , unintended consequences, that can cause more problems than you’re solving.” Epstein’s long-time business thesis is that the rich know little about the essence of money. They may know about generating it in their own businesses, but the great sums that result ,demand an entirely different sort of an intellectual discipline. The Forbes 400, says Epstein, not immune to still exhibiting an amount of wonder, increased their wealth by over $500 billion last year, meaning, in effect, that on average every Forbes-list billionaire increased their wealth by more than a billion only in one year. And, points out the 62-year-old Epstein, they will almost all be dead in 40 years, most well before that, meaning $4.2 trillion, compounding everyday, will have to be eventually change hands. “So, to understand the future, what you have to begin to do is follow the money, not in Watergate-like terms backwards, as in who has gotten it, but forwards to where it will go and who will get it.” Epstein can find himself echoing aspects of Thomas Piketty on the inequities of the accumulation of wealth (“the divide is between people with assets, which appreciate, and people without assets, who fail to advance—that is, of course, the miracle of compounded interest”), except for the fact that Epstein, knowing the rich, understands a curious point that Piketty doesn’t: “Nobody, nobody, wants to give it all to their children.
