I agree with what you are saying too. I would extend it to the 90s, at least till 95 when the whole Generation thing started to really change.
This last decade, so many JWs are depressed and unhappy an stressed that (as I used) the anxiety, depression card is being played by many Elders/MSs to get out of those roles. And it always works.
The hall I left had more people on Meds, and more divorces in total than the average population.
Besides ALL the failed timeline promises coming and going, a big factor that you alluded to is the CONSTANT message from the top that - YOU CAN NEVER DO ENOUGH - what ever you do is NEVER GOOD ENOUGH.
You get 10hrs a month - no you should get 15 - you get 15 you should aux pio - you aux pio really you should regular - you regular you should sever where the need is great.... and on and on at every level.
It is a religion that (unlike just about every other one) SUCKS YOUR SOUL DRY - instead of giving you a LIFT and a positive outlook - and joy. Guess that's why it is a cult.
I knew old GB like Sydlik and Barber. They were good guys, loving, kind, not mean or over bearing.
Sydlik would say - go do something fun, enjoy our life. He liked to watch Football and have a Scotch.
Those kind do not exist anymore.
And the vast majority of COs are just giant ass#oles now. We had a real string of COs that just Beat down the congregation.
I remember being a CO Pio meeting (I was an elder) and after this one meeting I had to console many of the pioneer sisters because the CO made them all feel like S#it.
This is what will eventually KILL the org and make it dwindle.
