In an analysis (pdf) published Thursday that throws into stark relief the “unjust and unsustainable” nature of what economists have termed the New Gilded Age, the Swiss financial firm UBS found that the wealth of the world’s billionaires grew by 17 percent in 2016, bringing their combined fortune to a record $6 trillion—more than double the gross domestic product of the United Kingdom.

“We’re at an inflection point. Wealth concentration is as high as in 1905.”

Josef Stadler, lead author of the UBS analysis, told the Guardian that the firm’s findings demonstrate that the world is “now two years into the peak of the second Gilded Age.”

The extent of the world’s wealth concentration—just eight men now own as much wealth as half of the global population—raises a number of questions, one of which is whether the world’s population will continue to tolerate such vast inequities, Stadler said.

“We’re at an inflection point,” Stadler argued. “Wealth concentration is as high as in 1905, this is something billionaires are concerned about. The problem is the power of interest on interest—that makes big money bigger and, the question is to what extent is that sustainable and at what point will society intervene and strike back?”

But despite insistence from leading economists and institutions like the International Monetary Fund that raising taxes on the wealthy is necessary to shrink the growing gap between the billionaires and everyone else, many global powers are doing precisely the opposite.
