Well, after serving for 25 years in different Federal Gov. dep. i can assure you that it is only few civil servents who are enjoying powers due to their official position and acting as serpents.
Ninety five percent are doing their job as "servents" and are always ready to adopt another profession if given a chance. You can verify this by the fact that once an officer retires, he thanks God to come out of this tension and enjoys a free life. On the other hand, the serpent type never wants to be retired and try his level best to get extension. But one day he has to be retired and finds life misrable and becomes ill. Several examples are there.
