There is a statement that To be an effective leader, a public official must maintain the highest ethical and moral standards. Some people agree on it, meanwhile the other people do not prefer it. From my point of view, I do not support it with my reasons.First of all, to evaluate leaders is not depending on the hight of their ethical and moral standards they hold, but lies in the qualities, abilies of them. To be a effective leader, must accomplish obligions with his or her group members in good efficiency. This calls for comprehensive qaulities and ablilities such as the abilities of communication, solidfing, judgements and so on. Since to be a effective leader who will confront virious problems and challenges, needs comprehensive abilities to solve them. There is a prime example of this, one leader of a Chinese company who can not express his meaning to his group members clearly, leading to his group members misunderstand his idea came out adverse effect to what thought of the leader. There are a great deal of this similar cases to convince us that other ablities besides highest ethical and moral standards are more important of a excellent leader.Second, leaders without highest ethical and moral standards can also reach success like those who have it, and sometimes owning highest ethical and moral standards of leaders may impede the development of the group. Since it is not a vital factor to be an effective leader. When we have other excelent qualities, the door of success is open for us, and the highest ethical and moral standards may give the leaders too much pressure to build a good image amoung the group members. After long time, the leader will feel tired and have so much pressure, which do not favor groups. And history filled with so many instances to support that excelent leaders do not require good ethical and moral standards. Such as Hitler whose ethical and moral standard are low still leaded his country and army to strong status.
