According to a new study from economists at the University of California-Berkeley, the Paris School of Economics, and Oxford University, from 2009-2012, average real income per family grew modestly by 6 percent.
However, the distribution of those gains was greatly tilted towards the richest one percent. According to the study, top one percent incomes grew by 31.4 percent while the other 99 percent saw incomes grow by just 0.4 percent from 2009-2012.
