See I think capitalism could work but the problem is like any object it can be turned into a weapon. When a very small minority has absconded the entire wealth of the world it leaves the majority without any resources while we are all engaged in a war against the human race and competition to survive resulting in a genocide of our weakest being consumed by this man made meat grinder.  By making competitors of one another we have doomed our species to hell. Civil we are not, peaceful we are not, pleasure we get from the pain of others.
