Humans, like animals in the book, tend to elect a leader and follow them blindly through life, even if they encounter many hardships. It is easy for humans to fall under the effects of a dictator. We as humans, tend to shy away from challenging authority. There is a point we must be pushed to, before we decide to revolt, and others must follow. Peer pressure is a large part of human nature. We all effect each other with our own actions. Society is digging a hole for itself that it may not be able to find its way out of.
Hope I helped.
