**Response to @RobertKennedyJr:**

From the end of WWII through the 1980s, income distribution stayed relatively constant. But union membership began declining, and the share of income going to the bottom 90% followed it. Capitalism only functions equitably if workers have the collective bargaining power of unions, so they can claim a fair share of the economic pie.
