When you consider how much more people are making, and how much less they are making in real terms, it becomes clear that the gap is widening.
It is estimated that by 2025, the world will be earning about $2.2 trillion less than the median income for all workers, according to the World Bank.
That would mean that the richest one-third of the world’s population would now be living on less than $10,000 a year.
The bottom 90 percent of the population, meanwhile, would be making more than $1.5 trillion a year less.
In the US, for example, the richest 1 percent of earners now make just $2,500 a year more than the bottom 99 percent, while the richest 20 percent earn only $1,000.
This gap is likely to continue to widen.
The number of people earning more than twice the median is expected to grow to 6.1 billion by 2025 from 5.7 billion in 2015, according the World Economic Forum.
The world is expected have around 2.5 billion people by 2050, with the number of millionaires in the world rising from around 675 million to more than 1.3 billion.
