There are those who want to control other people, and persuade themselves that they are doing a "service" when they do so. In the old days aristocrats were supposed to have a modicum of good sense and judgment, and the oath of fealty ran both ways, down as well as up; the lord was supposed to bear true faith to his subjects. Of course heredity was not a reliable way to select those with such awesome powers, and was replaced by counting noses to select the top people, who then select those they think fit to be the lords. So long as those on top did not stay there, and were as subject to the laws and restrictions as any others, this worked passable well, since those in charge did not have a great incentive to expand the command powers: after all, they too would be subject to them at some point.

But we now have career "civil servants" and career politicians, who will never be subject to the laws that govern the rest of us. Our masters have little incentive to restrict the scope and power of government. And if we thought taxation without representation was bad, think about what taxation with representation has achieved.
