"While ordinary people are making daily sacrifices on essentials like food, the super-rich have outdone even their wildest dreams," said Gabriela Bucher, Executive Director of Oxfam International.
"Just two years in, this decade is shaping up to be the best yet for billionaires —a roaring '20s boom for the world's richest," she stressed.
"Taxing the super-rich and big corporations is the door out of today's overlapping crises. It's time we demolish the convenient myth that tax cuts for the richest result in their wealth somehow 'trickling down' to everyone else," she added.
"Forty years of tax cuts for the super-rich have shown that a rising tide doesn't lift all ships —just the superyachts."
