“The bottom half of the world’s population owns the same as the richest 85 people in the world.”
The stat was quoted last month in a report by the development organization Oxfam, but similar claims have become common. You’ve probably seen this statistic—or one like it—before in articles about economic inequality and assumed they must be somewhat true.
But they aren’t. In reality, they are completely meaningless.
One of the problems is that the comparisons are based on net worth (assets minus liabilities). If you aggregate all the people who have a negative net worth into one category and call them the “bottom half” then you come up with some peculiar conclusions. As Felix Salmon says, “My niece, who just got her first 50 cents in pocket money, has more money than the poorest 2 billion people in the world combined.”
