Billionaire's wealth has grown faster last year, and now the world can expect at least five trillionaires within a decade, even as the number of people in poverty has barely budged since 1990.

Oxfam's report was released Monday. The annual meeting of elites held by the World Economic Forum think tank in Davos, Switzerland, formally starts on Tuesday.
