The old folks have been marginalized and no one really cares whether they're happy or not, nor do they care what they have to say. Unless they have quaint anecdote from yesteryear, when trotted out on the podium, their life experiences and observations are generally dismissed by the new ones who have entered upon the scene.
If you're not in the "young single" or " young married with kids " demographic, you could drop off the face of the earth and it wouldn't phase anyone. What the governing body said and did in the past and all of the sacrifices older JW's made as a result of their admonition, matters not, to anyone who came later. If you are old and disappointed, it's your own fault for reading too much into the information you read in the Watchtower, for being overly zealous and rushing ahead of Jehovah's chariot.
