There were several executives that everyone liked a lot. Greg Wilhere was one, not only was he better trained in Scn than David, Gregs wife was a super-star. Greg had a real mans appearance unlike David who had no stature. Greg also commanded respect and people did what he asked mostly from respect whereas with David it was just fear - Greg didn't shout much because he didn't need to.
Greg was viewed as man unlike David who was still a child running the show.
Norman Starkey was also up for the job as he was not only a genuine leader, but also was an actual seaman who outranked David until David removed his ranking - everyone knew David did this because he couldn't handle Norman being actually better trained then him.
David has a habit of cutting people down - especially men that were a lot taller than him (which is just about every man) but particularly the taller men.
Actually the reason why David liked having a lot of women about wasn't because he particularly wanted to screw them but because they did not physically intimidate him like men did - David often rose up the ranks in leaps and bounds just to be able to order men about about, he found comfort in the presence of women who were his size, and they complimented him a lot whereas the men questioned his insane judgement.
When David was younger he had a real problem with the other children overpowering him and he was isolated, even his own brother intimidated him, I remember at the Flag Land Base David got upset because his brother could show great feats of skill on the gym equipment (like hanging from his toes) and would laugh and get a long with the other men, David could never do any of this and lacked the ability to get a long with anyone.
This was another reason why David liked to use boys and girls as runners, I think in some way he tried to look after short people like himself and make them feel important - but the irony is when they would grow up and become stronger, better trained and independent, he would then crush them.
Greg Wilhere never did this because he had nothing to prove, and I think we should be thankful Scientology is not under his control because it would be doing much better then what DM is doing.
All the execs at RTC and CMOI know this - often execs at Int would have such thoughts come out in their Sec Checks and be punished for wanting a real leader, a man they could look up to rather than down.
