I thought these graphs were interesting. They show the median male and female income in the US relative to real GDP per capita.
Here's the male median income:
As you can see the median male income has stagnated since the early 1970s, whilst real GDP per capita has risen steadily. Now here's the female median:
Unlike male income, the median female income has risen steadily alongside the growth in real GDP per capita.
So it seems that large numbers of men haven't benefited from the growth in the US economy since the 1970s.
