trickle
探讨经济问题最好是脱离开政治立场，甚至脱离开自身的经济立场。
所谓tickle down economics, 其实是民主党批评共和党政策的一个虚假的概念，而这个概念从来没有被共和党提出过，或者支持过。
很多的减税政策是建立在投资和研究投入之上的，就像左派整天说贝索斯和巴菲特的税收上面，实际上那根本不是trickle down,这两人之所以当时少交税，存粹是因为，Amazon大量投入在AWS的研究和开发，巴菲特的钱都在继续投资，没有很高的收入。
当然这并不是说共和党没有在税收上考虑富人利益，事实上两党都是如此。最近纽森还豁免他的朋友panea bread不需付快餐界的最低工资法案。
Speaking on the Senate floor in 1992, Hank Brown (Republican senator for Colorado) said: "Mr. President, the trickle-down theory attributed to the Republican Party has never been articulated by President Reagan and has never been articulated by President Bush and has never been advocated by either one of them. One might argue whether trickle-down makes any sense or not. To attribute to people who have advocated the opposite in policies is not only inaccurate but poisons the debate on public issues."[64]
Thomas Sowell consistently argues that trickle-down economics has never been advocated by any economist, writing in his 2012 book "Trickle Down" Theory and "Tax Cuts for the Rich":
Let's do something completely unexpected: Let's stop and think. Why would anyone advocate that we "give" something to A in hopes that it would trickle down to B? Why in the world would any sane person not give it to B and cut out the middleman? But all this is moot, because there was no trickle-down theory about giving something to anybody in the first place.
