Escaping pain is human nature. There are only two means by which a man can satisfy his needs and desires: by one's own labor (this is the economic means) or by the appropriation of the labor of others (this is the political means). Appropriation is obviously much easier and less painful, thefore man always tends to employ it.
Understanding this principle, helps you better understand the essence of the State. The sub-tag "Escaping pain" groups books that analyse this topic.
