Check the table in green below

v      So why is the top earners share of all taxes so large? Answer, because they make most of the money. Their income has grown astronomically while the bottom 90 % of earners income have remained the same or decreased in last 20 years or longer.

v      From 1992 to 2011 Notice how the income of the top 10% has grown more than 10 times that of 1992

v      The Income of the lower 90% has not grown or has decreased

v      Because of the increase income of the top 10%, their total taxes have increased and their share of all taxes collected has also increased

v      Because the income of the lower 90% has not increased, their taxes have not increased and their share has decreased

v      The high income earners have seen their tax rate go down from 26% to 17% since 1992

v      Looking back even further to 1915, an era in which the Rockefellers and Carnegies dominated American industry, 

      the richest 1% of Americans earned roughly 18% of all income.

v      Today, the top 1% account for 24% of all income.The share of total income going to the top 1 percent of earners, which stood at 8.9 percent in 1976, rose to 23.5 percent by 2007,

but during the same period, the average inflation-adjusted hourly wage declined by more than 7 percent.
