As the rich, famous and influential meet at the annual World Economic Forum in Davos, Switzerland, aid agency Oxfam says billionaires should be made obsolete. And 200 millionaires agree. In an open letter addressed to world leaders, they say they want to pay more tax "for the common good".
The number of billionaires should be halved by 2030 through higher taxes and other policies to make the world a fairer place, Oxfam said at the opening of the Davos summit on Monday.
