If we accept the Laffer Curve as true (which I believe it is), then we may very well be on the wrong side of it. But I also would say that accepting its truth doesn’t mean that the curve can’t move through time, meaning that tax rates should be constantly examined.

That said, the bigger question truly isn’t “what tax rate gives us the most money?” but instead is “is getting the most money the economically efficient thing to do?” Are we using the money appropriately? Are we using it more efficient than the market would? And in that, I think you find the real debate. Beyond debating about the actual rate, debating about whether or not maximum government revenue is desired is the real issue.
