I was in one cong. as a child and up until my thirties.
I did not see this one man/woman in charge syndrome.
The original cong. servant before the elder arrangement was a very kindly unassuming but well organised man, his wife had been imprisoned as a pioneer for not joining up in the services in WW2 and their daughters even now in their 60's are really pleasant supportive elders wives (in the best possible way a jw can be) in their respective congs.
He worked for a living, owned a very modest home and was the nearest thing to a true Christian I ever met. If it wasn't for him I would have probably woken up and left around 1980 when everything jw-wise got harder and tougher. He taught me three scripture sermons at the age of 12 and was a genuinely good father and grandfather and he didn't make a fuss about beards and petty rules when other congs did.
He became the P.O. aged about 60 and carried on the same and of course the positions rotated for a few years.
The next P.O. was younger, 40's just as kind - a bit "look at me" and "big-headed" but he was reasonable and a solid decent hard working chap with a supportive wife and young family.
The next "permanent" PO was a younger again ex bethelite pioneer who had just been put on as a sub CO when his wife fell pregnant. This was a great leveller and again he was a kindly decent zealous chap with a supportive wife. Having young kids made him realise it wasn't easy in the real world and that helped his attitude enormously.
It was during his time I was appointed an elder on a large body of 15 or so. I did feel there was sometimes "a body within a body" but it wasn't two or three but about half a dozen older elders in their 40's through to 60's who perhaps got consulted and made decisions and got them rubber stamped by the rest of the body. But the rest of us would stand up to this when needed and they toed the line again.
But I heard horror stories within the circuit and often there were troublesome bodies of elders where there seems to be a little "Napoleon" at the helm and power struggles.
Queen Bee elders wives and their over-ruled elder husbands didn't seem to last long in our hall and they either moved away or resigned.
I sometimes wish my "home" cong was a bit more hard-nosed and unpleasant as I would have surely gone years ago!
