The difference between rich and poor is increasing worldwide, writes Oxfam Novib in its annual report on economic inequality in the world. The organization writes this every year before the start of the World Economic Forum (WEF) in Davos, a place where world leaders, CEOs, and international politicians meet annually to discuss world affairs.

Fewer and fewer people live in extreme poverty, concludes Oxfam. But the difference between rich and poor is increasing further and faster. Economic inequality is growing, among other things, because the richest people worldwide pay less and less taxes, writes the British aid organization.

Oxfam Novib writes, among other things, that the 2,153 richest people on earth now have more assets than the 4.6 billion poorest people.

The charity focuses in the report on the role of women who in particular take on unpaid work in poor countries, such as caring for the family and doing household chores such as cooking. These unpaid activities would have had a value of 11.9 trillion dollars (10.7 trillion euros) last year, Oxfam said. The aid organization writes that those activities add more to the global economy than the entire tech industry.

A place where many women still do unpaid work is Africa. According to the aid organization, the 22 richest people in the world would earn more than all the women in Africa added together. Oxfam calls the unpaid work "hidden engines in the service of a system that allows profits to flow away to large companies and their shareholders."
