It's not whether it works, but whom it appeals.

Trickle down economics is music to the ears of the rich. Despite people thinking that everyone's vote weigh the same, the rich has more influence than others, in the form of lobbying, or even through the sheer "legitimacy" that comes with wealth and fame, whether or not it's deserved. E.g. celebrities.

Politicians have more incentive to appeal to the rich and powerful, since those people hold the key to power. The vast majority of the populace are mere sheep who will fall in line.
