“In the United States, the richest 1 percent have seen their share of national income roughly double since 1980, to 20 percent in 2014 from 10 percent. This trend, combined with slow productivity growth, has resulted in stagnant living standards for most Americans.
No other nation in the 35-member Organization for Economic Cooperation and Development is as unequal, and none have experienced such a sharp rise in inequality.
In Denmark, the share of income going to the top 1 percent rose to 6 percent from just 5 percent. In the Netherlands, there was essentially no increase from 6 percent levels. Britain (6 percent to 14 percent) and Canada (9 percent to 14 percent) had notable increases in top-income earnings, but not as large as those in the United States.”
