Simplesally,
With all due respect, and I speak from first-hand experience, your information on the GB and other higher-ups seems more than a bit idealized.
I was in the same congregation with several, including Brother Knorr, and I can tell you they were seldom seen at meetings or out in field service. In fact, the prevailing attitude was to invoke Bethel work as a reason for their infrequent attendance. I've personally seen Knorr's field service report slips and they were nothing to brag about.
The only real exception I knew of was Fred Franz; I also understand that Jaracz makes a fairly earnest effort to play by the rules. Most, however, use their Bethel status as a justification to go easy on local meetings and field service.
As I indicated in a thread called ``Bethel memoirs'' some time ago, one of my regular duties was weekend receptionist at the 124 Columbia Heights building. I did that once a month. The first order of business every Sunday morning was for me to go to the newsstand at the Saint George Hotel and pick up 14 copies of the Sunday New York Times for distribution to the likes of Knorr, Suiter, Couch, etc.
So many of these higher-ups lolled around Bethel on weekends in slippers and casual attire that we referred to them as the ``Ban-Lon Brigade:'' a reference to the knit polo shirts so many of them favored on the weekends. They were more likely to be found raiding the kitchen for a snack than they were at their Kingdom Halls.
Of course, these ussually managed to find a way to report some token field service, mostly from talks they had given; but none of the local elders and even the Circuit Overseers had the temerity to take them to task. And, in most cases, the wives of the bigshots also got a pass, although I'm sure there were exceptions I'm unaware of.
Just my 2 cents.
