What is the status of income inequality around the world compared to the United States?

According to The Atlantic, income inequality is worse today than it was in 1774.  The rankings of inequality haven't changed much over two decades, but inequality is rising in most developed countries. No one knows absolutely why. The increase in income inequality has been greater in Canada than in the U.S. since the mid-1990s. I think income inequality has a bigger affect on the U.S. than it does in any other countries because our gap is greater than most others and the bigger the gap the larger the affect is.



Below are two different charts that illustrate the U.S. income distribution.
