More than 250 billionaires and millionaires are demanding that the political elite meeting for the World Economic Forum in Davos introduce wealth taxes to help pay for better public services around the world.

Our request is simple: we ask you to tax us, the very richest in society," the wealthy people said in an open letter to world leaders.

But it will turn extreme and unproductive private wealth into an investment for our common democratic future."
