What's behind growing economic gap?

Oxfam report says eight of the world's richest men have as much wealth as 50 percent of global poor.

The gap between the poor and the super rich is growing. The world's eight richest people have the same wealth as the poorest half of the entire world.

That's according to a new report by Oxfam, which describes this trend as obscene, unfair and grotesque.

The eight men are mostly American, including Microsoft's Bill Gates, investor Warren Buffett and Facebook's Mark Zuckerberg.

Oxfam warns this economic inequality threatens to pull societies apart and undermine democracy.

Its report says people have lost trust in their governments and are no longer willing to accept the status quo.

The anti-poverty organisation suggests that may help explain Donald Trump's victory in the US presidential election. And the UK's vote to leave the European Union. So what needs to be done to reduce wealth inequality?
