Oxfam, an international organisation says, eight men own the same wealth as half the world's population which threatens to pull societies apart.<br/><br/>Ahead of the World Economic Forum summit in Davos tomorrow, Oxfam, the confederation of charitable organizations focused on the alleviation of global poverty said, the wealth of the world's poorest 3.6 billion people is the equivalent to the combined net worth of six American businessmen, one from Spain and another from Mexico.<br/><br/>They include Microsoft founder Bill Gates, Mark Zuckerberg who co-founded Facebook, and Jeff Bezos, founder of Amazon, said Oxfam. The charity pointed to a link between the vast gap between rich and poor and growing discontent with mainstream politics around the world. It called for an increase in tax rates targeting rich individuals and cooperations, as well as a global agreement to end competition between countries to lower corporate tax rates.
