A new Oxfam report indicating that the wealthiest one per cent possesses about half of the worlds wealth has left the richest people in the world reeling with disappointment, a leading billionaire said on Tuesday. Speaking to reporters in Davos, Switzerland, where he is attending the World Economic Forum, the hedge-fund owner Harland Dorrinson said, I think I speak for a lot of my fellow billionaires when I say I thought we were doing a good deal better than that. Calling the Oxfam findings sobering, he said that he hoped they would serve as a wake-up call to billionaires everywhere that its time to up our game. Quite frankly, a lot of us thought that by buying politicians, rewriting tax laws, and hiding money overseas, we were getting it done, said Dorrinson, who owns the hedge fund Garrote Capital. If, at the end of the day, all we control is a measly half of the worlds wealth, clearly we need to do moremuch more. In Davos, Dorrinson is huddling with other billionaires in the hopes of setting an ambitious goal for the top one per cent: to own the other half of the worlds wealth by 2025. While he considers this target doable, Dorrinson said that he does not underestimate the challenge of wresting the other half from the vise-like grip of the approximately seven billion people who comprise the bottom ninety-nine per cent. Getting that other half is not going to be a walk in the park, he said. But ten years from now, when Oxfam says that the top one per cent owns everything in the world, itll all have been worth it.
