According to de Vries, the super-rich are increasingly succumbing to what has been labelled Wealth Fatigue Syndrome (WFS). When money is available in near-limitless quantities, the victim sinks into a kind of inertia.
"The rich are never happy, no matter what they have," he told CNN. "There was this man who owned a 100ft yacht. I said: 'This is a terrific boat.' He said: 'Look down the harbour.' We looked down the marina, and there were boats two and three times as large. He said: 'My 100ft yacht today is like a dinghy compared to these other boats.' When else in history has someone been able to call a 100ft yacht a dinghy?"
Some of our friends have jumped from nice five-bedroom houses in South Kensington to gated mansions in St John's Wood, complete with hot and cold running staff. But many who join the super-rich find it hard to keep their old circles of support. Happiness studies have repeatedly shown that being marginally better off than your neighbours makes you feel good, but being a hundred times richer makes you feel worse. So either you change your friends or live with the envy of others.The article goes on to expound numerous other causes of wealth-induced misery: social support networks break down, as relationships with old friends are strained by the wealth disparity and poisoned by real or perceived envy; and all the cars, yachts and new houses your money can buy you just become boring much more quickly. (It's the hedonic treadmill effect, where one becomes acclimatised to one's level of comfort and contentment, it takes even more to not succumb to ennui.) Meanwhile, the wives of the super-rich (and most of the super-rich are men; presumably husbands of super-rich women or gay partners would suffer the same) suffer the same psychological consequences as the unemployed (that is, when they're not traded in for younger, prettier models), and their children, shuttled between nannies and estates, often end up clinically depressed.
The conclusion is that money can buy happiness — but only up to a point. A key component of happiness is social connectedness, of the sort that cannot be bought:
The happiest nations, he says, are those where people feel most equal, even if that means being less wealthy. Pentecost, a tiny island in the South Pacific, has recently been voted the happiest place on earth. They don't have WFS – in fact, they don't have money; they use pigs' horns instead.
In places such as Pentecost, people actually talk to each other – indeed, belonging to a community is one of the single most important prerequisites for happiness.
