wage gains have gone largely to the highest earners. Since 2000, usual weekly wages have risen 3% (in real terms) among workers in the lowest tenth of the earnings distribution and 4.3% among the lowest quarter. But among people in the top tenth of the distribution, real wages have risen a cumulative 15.7%, to $2,112 a week – nearly five times the usual weekly earnings of the bottom tenth ($426)….
in 2016 Americans in the top tenth of the income distribution earned 8.7 times as much as Americans in the bottom tenth ($109,578 versus $12,523). In 1970, when the analysis period began, the top tenth earned 6.9 times as much as the bottom tenth ($63,512 versus $9,212).
