I hear you. I think it's clear Bill's "aww shucks" attitude with his sweater selection is a page from Buffet's playbook to make himself appear more likeable. The truth is, he wants control over every aspect of human society, to a level that makes him a clear psychopath.
He's got the dupers delight smirk on his face every time he talks because he can't hide his glee over getting to push his agenda. Corbett's documentary on Gates tells you all you need to know.
MMMM...mmmm. does that mean his wife is also a psychopath? oh its so hard huh! well never know really
Likely. Unfortunately, psychopathy is fairly common among the elite class.
