Whats intriguing about the eruption of Occupy Wall Street is that its so similar to other populist movements that are demanding change in nearly every major region of the world. You cant help but wonder if we arent seeing, as a delayed reaction to the financial crisis of 2008, a kind of global spring of discontent. Obviously, circumstances differ: The anti-corporate activists gathered in Manhattans Zuccotti Park have a different agenda than the demonstrators in Cairos Tahrir Square, or this past summers rioting street protesters in Britain and Greece, or the anti-corruption marchers in New Delhi. These movements mostly lack leaders or clear ideologies, so theyre hard to categorise. But the protesters do share some basics: rejection of traditional political elites; a belief that globalisation benefits the rich more than the masses; anger about intertwined business and political corruption; and the connectedness and empowerment fostered by Facebook and other social media. This neo-populism is all the more striking because it seems to transcend traditional political boundaries. The Tea Party movement may wear conservative colours, but it arose as a protest against elites in Washington and on Wall Street who were seen to be profiting at the expense of everyday people. Occupy Wall Street comes at these same issues from the left, but the two movements have much in common. The Arab Spring is the worlds most potent populist movement, sweeping away governments in Tunisia, Egypt and Libya. These uprisings began as leaderless explosions of indignation - blurring the usual lines of capitalist and socialist, Muslim and Christian. These cleavages have returned, especially in Egypt. But the core of the revolution there remains a rage against traditional elites. Protests in Europe have the same note of mass indignation. In Greece, Italy and even France, you see the anger of the middle class that their debt-enfeebled governments cant deliver on welfare-state promises. In some countries, such as Britain and Germany, there is unrest, too, among growing immigrant populations that are not tethered to national cultural or political norms. Even in the boom countries, such as China and India, there is the turmoil that comes with rising expectations. According to Chinas Ministry of Public Security, the country experienced 87,000 incidents of popular unrest in 2005. Thats 238 protests a day The Chinese stopped publishing the number after that, but it surely hasnt gone down. India, too, has seen a rising tide of protest, symbolized by the mass street marches in the summer that surrounded Anna Hazares hunger strike to protest corruption. Its a stretch, perhaps, to look for shared themes in such disparate countries. But these movements seem to have a common indignation toward leaders who are failing to maintain social justice along with global economic change. Thats certainly true in America, where the Tea Party and Occupy Wall Street both rage against a financial elite that stumbled into a ruinous recession - and then got bailed out by a Washington elite thats in hock to special interests. The Tea Party, especially, tapped the bedrock American mistrust of big banks, which dates to Thomas Jefferson and Andrew Jackson. Growth and prosperity would restore public confidence, as in the past. But this time, the anticipated recovery - and deflation of popular anger - still seems a few years away. Europes neo-populism will surely increase, as countries struggle with painful economic adjustments. Population is declining in most of Europe, which means there will be fewer young workers to pay for the pensions of retirees. To regain competitiveness and solvency, wages and the quality of life will have to decline in many European countries. Meanwhile, according to a recent study by the National Intelligence Council, by 2025 Western Europes Muslim population could increase to 25 million to 30 million from the current 15 million to 18 million, causing additional strains. Theres no sign yet of a new European political leadership that can accomplish the necessary rewrite of the social contract. Much of the worlds neo-populist anger is justified, given the greed and folly of recent years. What worries me is the echo of the 1930s, a similar period of economic change and dislocation. When the traditional business and political leaders seemed to have failed during the downturn of the 30s, populist indignation veered sharply right and left - toward dangerous movements that expressed national indignation at the point of a gun. America was lucky then to have had, in President Franklin D. Roosevelt, a charismatic politician who could rehabilitate the center. And now? Not so lucky. Washington Post
