Evolution.

How did 65 people end up with as much money as half the population of the planet?  Why would someone like the Koch brother two of the richest men on the planet want more, more, more? Why after they have accumulated over a hundred billion dollars do they want to destroy American democracy, drive the working class into poverty and destroy all social safety nets?  Why can't the Koch brothers and all the other greed dogs just sit on their yacht, fly in their jet, go to their fifth multimillion dollar home and just leave the rest of the world alone?  Why do they need more tax breaks?  What drives these people to want to control the world and cause the suffering they do with the greed that has driven them insane?
