No. Trickle down economics refers to things that benefit the wealthy (mostly government policies, particularly related to taxes and subsidies) that will allegedly benefit everyone by “trickling down.” Supply-side economics are an example of trickle-down economics. Trickle-down economic policies have been shown to effectively increase income inequality and studies suggest a link between them and reduced overall growth.

Giving the wealthy tax breaks in the hopes that they’ll spend the extra money they have available on security details, on the other hand, would be an example of trickle down economics.
