I don't understand. Can you elaborate?

The Laffer curve simply shows the relationship between taxation and government revenue. It has nothing to do with the policies and the economic theories. In fact, there are two points on both sides of the Laffer curve's maxima where tax revenues are the same in theory. That's just a simple didactical tool, nothing more.

Saying that the Laffer curve is the trickle down economics is as bad as saying that visualizations of a binary tree are what we call algorithms and data structures.
