About the Word:
Kakistocracy is one of those inexplicably uncommon words; a small bit of language that is so obviously useful that it boggles the mind that children are not taught this word in some early developmental stage, along with cat, more, and mine. It seems that a large number of people in every generation believe themselves saddled with a kakistocracy, and if we are being cynical (by which I mean realistic), they are probably all correct.
Example:
"... transforming our old Hierarchy into a new Presbytery, and this againe into a newer Independency; and our well-temperd Monarchy into a mad kinde of Kakistocracy. Good Lord!" - Paul Gosnold, A Sermon, 1644
