Laffer curve models tax revenue as a function of a single tax rate.
Given the table above, it suggests that the tax cuts led to less revenue from the lower income groups ie there was a reduction in the taxes from the bottom 50%. But it led to more revenue from higher income group people ie the top 1%.
This implies that the reduction in the top marginal rate made atleast fiscal sense.
The Laffer Curve is based on supply-side economist Arthur Laffer's theory. It was developed in 1974 to illustrate the relationship between tax rates and the amount of tax revenue collected by governments.
The curve is frequently used to demonstrate the point that lowering tax rates can result in increased total tax revenue.
