Trump and other Republican politicians are trying their best to revive their nonsensical horse-and-sparrow supply-side rationale so the rest of us can pay to make the rich far richer.
Trickle down used to be called horse and sparrow. The idea was that if a horse ate a whole lot of oats, some wouldn't get digested and the sparrow could eat them. I wonder why they don't use that metaphor today 🤔
