The International Monetary Fund has been urging governments to provide more money to their citizens, but in some places the gap between the rich and poor remains wide.
In the US, where President Donald Trump campaigned on a pledge to bring back millions of jobs, the gap has been growing in recent years, with the gap reaching a record high in 2015, according to data from the US Census Bureau.
A new report by the International Monetary Group (IMF) says some of the biggest gains in the United States have been in the bottom third of the income scale.
The report says some cities in the US have been hit hard by the recession, and that this has helped drive a rise in income inequality.
The study notes that in the same period, the bottom 20 percent of US households saw their incomes rise by almost $1,400 a year, while the top 20 percent saw their income fall by $2,200 a year.
“While the US economy has been doing better than many other developed countries in the last few years, income inequality is still the biggest challenge facing the country,” the IMF said in a statement.
The US has the world’s third-largest economy and the fourth-largest wealth, with a gross domestic product of more than $1 trillion.
It is the world leader in high-speed rail, a major supplier of the global internet and one of the largest suppliers of renewable energy.
