When you say "trickle down economics" I assume you mean the idea of tax cuts and smaller government, more Capitalism, less Socialism. Lets go with that analogy for now.
Ok, so, please post for me all the great Socialist economies in the world.
I can think of some real time Socialist Disasters, Venezuela comes to mind where folks are literally starving in what was the richest country in South America with vast natural resources, and embraced Socialism and Central planning.
Then look at Singapore, with zero natural resources, embraced Capitalism and the place is a monument to opulence.
Socialism has never worked anywhere since recorded history. Then next time it works will be the first time.
Capitalism OTH, has created more wealth for more people in the history of the world.
