Sorry Dilbert, I must disagree with you and your description of the "upper echelon". While I don't want to boast about my psychological prowess, I know a friend of a friend whome I have discussed this topic with in depth and I think it's time to get more clarity on the subject.
While I do concur with the "lack of conscience" part of the sociopath diagnosis, my friend of a friend clearly indicates that a more clinically correct diagnosis, in particular however not exclusive to the non-Swire managers, would be "a Sycophant with Sociopathic tendencies".
Sycophant - "a self-seeking, servile flatterer; fawning parasite" (Dictionary.com)
