30 years have accomplished exactly what was set out to be accomplished. It's now considered acceptable for a CEO to make over 1000 times what the guy actually creating value makes. Well, acceptable by anyone with an MBA, and you don't have one, so what do you know you moron get back to work, and don't worry your head about what percentage you take home of what you produce.
Trust me, they knew what they were doing with `trickle down'. It's based on the premise that, given an arbitrary level of national economic output, people who have more money should get more money. The question of who doesn't get it is left as an exercise.
