Over the past decade, calls to tax the rich have grown louder all around the world.

That's the age of the poor.

We won't take it anymore.

You want to make a million or millions of bucks, that's great.

Just pay your fair share in taxes but the needle

hasn't exactly moved billionaires are still amassing incredible amounts of

wealth and they are paying less in taxes than they have in decades.

The Brazilian government has a new proposal, a 2% global wealth tax on the Uber rich.

It would affect the 3,000 wealthiest people in the world.

2% might not sound like a lot until you consider just how much

billionaires are paying in taxes right now.

It is something like 0.3% of their wealth, according to a new report commissioned by the G20.

Economists say this 2% hike would unlock an extra $250 billion a year, and that money could go toward addressing a number of issues like

climate change or global poverty.

But there's still a question of feasibility.

How do you coordinate a global tax?

G20 nations would have to agree on this proposal

before it goes anywhere, and so far that isn't happening.

France, Spain, South Africa, and several other nations

have voiced support, but the US and Germany are not on board.

Consider this. Billionaires are getting richer and calls to tax the Uber rich are getting louder.

Is a global wealth tax a feasible solution?
