The Occupy Wall Street protest against income disparity spread across Western Europe, Asia, the U.S. and Canada today. Rome's demonstration turned violent, contrasting with peaceful events elsewhere. The rallies started last month in New York's financial district, where people have been staying in lower Manhattan's Zuccotti Park. They widened to 1,500 cities today, including Sydney and Toronto, the organizers said, in a global day of action against Wall Street greed." Protesters say they represent "the 99 percent," a nod to a study by Nobel Prize-winning economist Joseph Stiglitz showing the top 1 percent of Americans control 40 percent of U.S. wealth. In Berlin, 6,000 took to the streets and 1,500 gathered in Cologne, ZDF television said. In Frankfurt, 5,000 marched by the European Central Bank headquarters. In New York, demonstrators marched past a JPMorgan Chase & Co. branch urging clients to transfer accounts to "a financial institution that supports the 99 percent." They distributed fliers with a list of community banks and credit unions. New York police arrested 24 at a Citigroup Inc. bank branch and 6,000 gathered in Times Square. About 1,000 people gathered in Toronto's financial district carrying signs saying "Nationalize the Banks." Demonstrations turned violent in Italy, where the unemployment rate for 15-to-24-year-olds was 27.6 percent in August.
