The wealthiest have seen their net worth soar over the five years ending in 2015. Back in 2010, it took 388 mega-rich people to own as much as half the world. And the Top 1% own more than everyone else combined -- a milestone reached in 2015, a year earlier than Oxfam had predicted. Oxfam released its annual report ahead of the World Economic Forum in the Swiss cityof Davos, a yearly gathering of political and financial leaders. The study draws from the Forbes annual list of billionaires andCredit Suisse's Global Wealth Databook. The anti-poverty group, whose leader co-chaired the forum last year, wants to call even more attention to the widening wealth divide. The top 62 saw their net worth rise by more half a trillion dollars between 2010 and 2015, while the 3.6 billion people in the bottom half of the heap lost a trillion dollars. Each group has $1.76 trillion. "Wealth is moving rapidly to concentrate at the tippy, tippy top of the pyramid," said Gawain Kripke, the director of policy and research at Oxfam America. http://money.cnn.com/2016/01/17/news/economy/oxfam-wealth/index.html
