In a report released ahead of the World Economic Forum in Davos, Oxfam said it estimated that unpaid care work by women added at least $10.8 trillion a year in value to the world economy -- three times more than the tech industry.

Alexandra Ocasio-Cortez, the Democratic congressperson from Queens, says the “system” that creates billionaires is wrong.

Billionaire fortunes increased by 12 per cent last year — or $2.5 billion a day.

Collectively, the five tech firms lost $172 billion in just a few hours.

Oxfam released a report, saying there were 233 more individuals who became billionaires between April 2016 and March 2017, the highest in any year. 

The good news - a number of the world's wealthiest are known to be very generous.

It's that time of the year: Forbes has released its list of the world's richest people. Roughly 1,800 billionaires made this year’s list, with a total net worth of $6.48 trillion.
