Two key findings from a recent report:

  • The wealthiest Americans have collected the bulk of the past three decades’ income gains. The share of national income of the richest 1% more than doubled between 1980 and 2008: from 8% to 18% [Table 9.1]. The richest 1% now makes an average US$1.3 million of after-tax income (compared to US$17,700 for the poorest 20% of US citizens). During the same time, the top marginal income tax rate dropped from 70% in 1981 to 35% in 2010.
  • The rising incomes of executives and finance professionals account for much of the rising share of top income recipients. Moreover, people who achieve such a high income status tend to stay there: only 25% drop out of the richest 1% in the US, compared to some 40% in Australia and Norway, for instance.
