Reforming the very nature of capitalism will be needed to combat the growing appeal of populist political movements around the world, the World Economic Forum said Wednesday.

Getting higher economic growth, it added, is necessary but insufficient to heal the fractures in society that were evident in the election of Donald Trump as U.S. president and Britain's vote to leave the European Union.

In a wide-ranging report from the organizer of the annual gathering of political and business leaders in the Swiss resort of Davos, the WEF identified "rising income and wealth disparity" as potentially the biggest driver in global affairs over the next ten years.

As an example of this growing inequality, the WEF highlighted the massive increases in CEO pay at a time when many people in advanced economies have struggled to make ends meet following the global financial crisis.

"This points to the need for reviving economic growth, but the growing mood of anti-establishment populism suggests we may have passed the stage where this alone would remedy fractures in society: reforming market capitalism must also be added to the agenda," it said in its latest Global Risks Report.

"The combination of economic inequality and political polarization threatens to amplify global risks, fraying the social solidarity on which the legitimacy of our economic and political systems rests," it added.

That's some conclusion from an organization that's sought to play a central role in the globalization process of the past couple of decades and that is closely identified with some of the world's richest people.

As well as getting growth higher, the WEF identified four areas that need to be addressed urgently: the need for long-term thinking in capitalism; a recognition of the importance of identity and inclusiveness in political communities; mitigating the risks and exploiting the opportunities of new technologies such as driverless cars; and strengthening global cooperation.

Risk to mainstream politicians

It added that a failure to address the underlying causes of the populist tide poses a threat to mainstream politicians and raises the risk that the globalization trend will go into reverse.

"Some people question whether the West has reached a tipping point and might now embark on a period of de-globalization," it said.

Although anti-establishment politics have tended to blame globalization for the loss of traditional jobs, the WEF said rapidly changing technologies have had more of an impact on labor markets.

"It is no coincidence that challenges to social cohesion and policymakers' legitimacy are coinciding with a highly disruptive phase of technological change," the WEF said.

Other key drivers identified in the survey of global risks related to climate change, rising cyber dependency and an aging population.

The 2017 report, the 12th annual report, is based on an assessment of 30 global risks by 750 experts from a variety of backgrounds, including business, academia and non-governmental organizations.
