Year 2007 is therefore the second highest year on record since 1913 almost equalling 1928, the record year when the top percentile share reached 23.9% . . . .
Even within the top percentile, the gains from 2006 to 2007 are extremely concentrated. The top .01% (top 14,988 US families, making at least $11.5m in 2007) share increased from 5.46% in 2006 to 6.04% in 2007 leaving well behind the 1928 peak of 5.04% . . . . the top percentile captured 65% of total real income growth per family from 2002 to 2007[.]
The top 10% of income earners received about half of all income in 2007.
Of course, 2008 and 2009 serious depleted many of these high incomes and has also reduced wealth inequality.
