One other question with respect to government types has always bugged me, and that is where does a Monarchy fit in. Does it come under Type A or B, or Type 5, Feudal Technocracy, or maybe even Type 3, Self-Perpetuating Oligarchy. The latter two because based on the history of Earth monarchies, there has always been an underlying upper aristocratic class that they depend on for support.
Monarchy does not fit in, as it can be of any government type from the family
corporation dedicated to making profits (type 1), through Religious dictatorship
(John made England a vassal state of the Papacy), to Totalitarian Oligarchy (type F).
Kind Regards
