The idea behind trickle-down economics is that wealth gradually percolates through the various layers of society and eventually everyone will be better off. There are three problems with this theory. First, trickles are far too slow and inadequate. Nobody wants a poxy trickle of wealth filtering through to them in the cheap seats down below, drop by drop. "Thanks for that trickle!" are the words they will never cry. A waterfall, fast and furious, and very quick, would be more acceptable. A better and faster way to spread the wealth around is by use of one strong sharp attack with an effective tax law. That's faster and more satisfying than waiting for scraps to fall down from the rich man's table.
The world looks like a rational place, everything functioning according to immutable universal principles, economies growing and people thriving as they experience lives of increasing abundance…until you bring in the twin notions of Justice and Equality. That’s where it all begins to unravel.
