I think we would both agree that a 1% tax rate would take in very little, as would a 99% tax rate.
Laffer simply said that somewhere between 0% and 100% is the ideal rate for raising revenue, and that there are points on the curve where you can increase revenue by lowering the rate.
We can argue all we want about where the ideal rate is, but on what basis do you state that the curve itself is a fraud?
