With an expanding share of the gains from economic growth flowing to a tiny fraction of high-income US households, average family income for the bottom 90% has been flat since 1980. According to a recent report by the Council of Economic Advisers, if the share of income going to the bottom 90% was the same in 2013 as it was in 1973, median annual household income (adjusted for family size) would be 18%, or about $9,000, higher than it is now.
