For those of you on this board who understand why the rich will always get a bigger share of any tax cut, i.e. the perennial left wing demagoguery of "tax cuts for the rich", you may ignore the video.
For those of you who seek to understand the math of a tax cut carried out in a progressive income tax scheme (our current tax system). Please enjoy the video.
For those who want to continue the demagoguery, God help you and your jealous souls.
