The Laffer Curve is usually misunderstood. The professor is not responsible for this.
Conservatives and liberals both often seem to think the LC says that reductions in tax rates will always result in increases in revenues. This is inaccurate.
There is a peak in the curve where the maximum revenue is produced. It a system is to the right of that peak, increases in tax rates will cause a drop in total revenue.
But if one is to the left of the peak, increases in tax rates will cause an increase in total revenue.
Both liberals and conservatives, when discussing the LC, always seem to assume we are on the right side of the peak. But that doesn’t necessarily follow.
Before attempting to use (or discredit) the LC, one should demonstrate why we are presently left or right of the peak.
It, the Laffer Curve, has worked every single time it has been tried and that's why the libs hate it!!!
This completely liberal author is a hold-over from when MarketWatch.com was known as CBSMarketWatch.com. This entire piece is a gigantic steaming pantload to put it mildly IMO!!!
