Government is force, violence and coercion. It is not reason or cooperation. The bigger it gets, the more force and violence. When it is minimal, force and violence is minimal and just used against evil doers, criminals. As it grows it gains more and more victims.
Absolutely correct. Power corrupts and absolute power corrupts absolutely, whether vested in an individual or a class.
Limited government can be controlled by the election process. Massive government cannot be controlled by any means short of God's impending doom.
