'Obscene inequality': Oxfam says taxing the world's richest could help save lives - CNBC

A 99% windfall tax on the pandemic gains of the world's 10 richest men would raise enough money to pay for vaccines for the world — as well as finance various social measures for more than 80 countries, the report said.

One way to "claw back" the huge gains made by billionaires during the crisis is to tax the money that billionaires have made since the start of the pandemic, the report said.

Even after the tax, the world's 10 richest men would still be billionaires and as a group, would have increased their wealth by $8 billion from the start of the pandemic, the report said.
