EXPLANATION OF ALTERNATIVE:
20
Though not shown on this chart, the effective tax rate on incomes over $1,000,000 AGI in 1980 was 48%.
21
In 2009 the effective tax rate on the highest income bracket (i.e. over $10 million) was 22.5%; i.e. 25.5 pts less than in 1980.
22
If the average increase in the effective tax rate on incomes over 500,000 was increased by 20 pts, the total potential additional revenue would be $248 billion.
