Holly Peterson （daughter of Peter Peterson) and I spoke several times about how the super-affluence of recent years has changed the meaning of wealth. “There’s so much money on the Upper East Side right now,” she said. “If you look at the original movie Wall Street, it was a phenomenon where there were men in their 30s and 40s making $2 and $3 million a year, and that was disgusting. But then you had the Internet age, and then globalization, and you had people in their 30s, through hedge funds and Goldman Sachs partner jobs, who were making $20, $30, $40 million a year. And there were a lot of them doing it. I think people making $5 million to $10 million definitely don’t think they are making enough money.”

As an example, she described a conversation with a couple at a Manhattan dinner party: “They started saying, ‘If you’re going to buy all this stuff, life starts getting really expensive. If you’re going to do the NetJet thing’”—this is a service offering “fractional aircraft ownership” for those who do not wish to buy outright—“‘and if you’re going to have four houses, and you’re going to run the four houses, it’s like you start spending some money.’”
