If Apple CEO Tim Cook sells a computer to me, the money I pay for it doesn't "trickle up" to Apple. Apple earned it in exchange for selling me the computer. If an employee of Apple works to produces the computer, the money he receives doesn't "trickle down" to him. He earned it in exchange for his production.
Even worse, the implication of the so-called "trickle down" catch-phrase is that the workers and consumers receive less from capitalism than what they've earned or are entitled to. In fact, they receive not only what they are properly entitled to; they receive in addition a bonus, which they would not have been able to create or produce on their own.
How many of the employees or consumers of Apple or Microsoft could have invented the technology they benefit from were it not for entrepreneurs like Steve Jobs or Bill Gates? If there is an appropriate metaphor to describe the benefits the average person receives from innovative capitalists like Jobs or Gates, it is not "trickle down" economics but "cascade down" economics. It is an economic system that gives workers and consumers benefits that far exceed what they could have invented or produced on their own.
