charts tell the story of changes in income distribution in the
U.S. in two periods since 1947. Between 1947 and 1979, when the U.S. economy was based
on goods and services production and consumption, income gains were
evenly distributed among income groups, averaging from 7.17% to 9.83%
annually across all groups. As the U.S. economy became dominated by
finance starting in the early 1980s, average annual income gains remained close to 7% for the top 1
percent group, but fell to 0.24% for the lowest fifth.
After 2004, distribution of real
income gains became even more extreme: negative for 90% of
wage earners and up as much as 16% for the top 0.6%.
