The wealthiest 1% will soon own more than the rest of the world's population, according to a study by anti-poverty charity Oxfam. The charity's research shows that the share of the world's wealth owned by the richest 1% increased from 44% in 2009 to 48% last year. On current trends, Oxfam says it expects the wealthiest 1% to own more than 50% of the world's wealth by 2016. The research coincides with the start of the World Economic Forum in Davos. The annual gathering attracts top political and business leaders from around the world.
