My father once told me a story about the Ducabores, a tribe in the wilds of Siberia. It seems that a rare species of potent psychotropic mushroom grew in their region and, when ever some of the mushrooms were found, it was cause for great celebration. On the evening of the find, the women brewed a strong tea from the mushrooms. However, because the mushrooms were very rare, only the headmen of the tribe (the leaders and wealthiest) could have the tea. The good news was that the tea lost only a little of it's potency as it passed through the body so, the lesser of the tribe waited for the inevitable, cups in hand near the tribal latrine. When the headmen came to relieve themselves, the precious, golden liquid was captured in the waiting cups so that all in the tribe could share in the good times.
When ever I hear someone use the term "trickle down economics", this image leaps to mind.
