@ican711nm,
1980 to 1988:
Fed Receipts %Increase = 75.8%, or increased by a factor of 1.758;
US Inflation %Increase = 40.94%, or increased by a factor of 1.4094;
US Civil Population %Increase = 10.06%, or increased by a factor of 1.1006;
US Civil Employment %Increase = 15.78%, or increased by a factor of 1.1578.
Federal Receipts Increase factor is less than the product of Inflation increase factor, US Civil population Increase factor, and US Civil Employment Increase factor = 1.4094 x 1.1006 x 1.1578 = 1.796.
But Inflation and Population increases did not increase taxable incomes or Fed Receipts in 1980 to 1988. Fed Receipts were increased by increases in taxable incomes and increases in the number employed. Both of these were increased by reducing taxes on incomes from 70% to 33%.
