Orthogonality and leadership
Those who sing the praises of leadership or of certain types of leadership may encounter problems in implementing consistent leadership structures. For example, a pyramidal structure in which authority consistently emanates from the summit can stifle initiative and leave no path for grooming future leaders in the ranks of subordinate levels. Similarly, a belief in universal direct democracy may become unwieldy, and a system consisting of nothing but representative leaders may well become stymied in committees.
Thus many leadership systems promote different rules for different levels of leadership. Hereditary autocrats meet in the United Nations on equal representative terms with elected governments in a collegial leadership. Or individual local democracies may assign some of their powers to temporary dictators in emergencies, as in ancient Rome. Hierarchies intermingle with equality of opportunity at different levels
