Those of us fortunate to have worked behind the scenes with all kinds of leaders have the unique perspective that, actually, none of these people have any more control over the world than anyone else. The illusion of control implies an assumption that people "under" their rule daily relinquish their wills in return for parental protection from uncertainty. No one does. People willingly do what they do. It is an inaccurate conclusion to think that any human being can take responsibility from another. This doesn't mean leaders are useless. Many have much to offer, starting with reminding people of their intrinsic freedom and responsibility that becomes the basis for their authentic engagement, consciousness and growth.
