Again, it's been utterly disproven - there is no trickle down effect and there hasn't been for the hundred plus years this theory has knocked about.
Everything you just said is the textbook theory that has absolutely no basis in real practice anywhere in the world.
What has worked is tax breaks for small businesses, driving up the core of an economy which in turn generates a strong economy from the bottom up, not top down. I'm not advocating "socialism" here - I'm saying that the very rich getting richer results in absolutely nothing other than the very rich getting richer.
