Power corrupts??

Does Lord Acton's statement: "Power tends to corrupt; absolute power corrupts absolutely" rings true for all those in power?

I've seen several people who used to be nice and decent turning into political monsters once they became managers, ignoring and/or back-stabbing the very people that they are suppose to be taking care for. 难道这就是所谓的：“小人得志，鸡犬升天“?

Once one attain a managerial status, one will realise that out of the blue one seems to be surrounded by 'friends'. There is no lacking in those who like to say "Let me tell you something that so-and-so said about you the other day." who suddenly seems have your interest in mind. And you will notice too that those in managerial positions tend to be a bit hard on their hearings (except good things that were said about them) and blind to what is happening right in front of their eyes...

俗话说：“有多大的头就戴多大的帽”。没有那份能耐就别害人误己，因为自己的无能，领导无方却放不下身段承认，就拿下属开刀。有时搞到做不成同事，连朋友也无法做下去。就多那几百块钱和一个死了带不走的经理/总裁头衔，值得放冷箭、撕破脸、弄得自己名誉扫地，千夫所指吗？？
