By the way, a tax of up to 5% on the world’s multi-millionaires and billionaires could raise $1.7 trillion/year.

That would be enough to lift 2 billion people out of poverty and fund a global plan to end hunger.

We can't afford NOT to tax the rich.

@rbreich You know that 5% per year is losing half your assets from taxation in 13.5 years, yeah?

You'll have better luck with a 1% rate; that'd erode half the value over 69 years.
