In the end, all republicans believe that people should take care of themselves and that because the government is inherently evil, can't be trusted to take care of anything or anyone. So, since people should only take care of themselves... we should stop taxing the wealthy so that they will then use all of those savings to take care of the rest of us.
Because, obviously, let's let a handful of historically self-serving people do the right thing. Because of course they will. If we choose to divide and elect a thoroughly partisan government that, by design, can not possibly function, then of course we were right all along about it not being able to to function!
Basically, republicans are the biggest morons on the planet. They suffer daily from the fundamental truth that their ideology is completely broken and that they can only make terrible decisions in life. As long as there is a convenient minority to blame, though, all is good.
