I agree that the recent meeting changes were an effort to make life a little easier for the elders. Conducting the CBS was a pain for many, now they only have to do it maybe once every 4-8 weeks (depending on how many elders there are). Also, the TMS parts that were cut were ALL handled by elders/ms. So, less parts to work up.
The last CA had a part about "reaching out" because there is a huge need for local leadership. However, many burned out elders that I've spoken with have no intention of "serving" again, even if they believe the religion. I'm sure there are also those that simply don't believe any longer but continue to attend for various family reasons.
I'm sure the WTS is aware of the problem not only with those stepping aside, but the fact that many elders are elderly. You simply can't get the work out of the old ones that you can out of the young one.
There are still men wanting to attain that position. In the congregation I attend, they just appointed someone in their late 20s as an elder. The difference is that you used to see that fairly frequently and in the last 5 years, that was the first person appointed. The ms pool is very thin and seems to me to be filled largely with folks who will never be able to be promoted to elder.
My guess is they will eventually need to start consolidating congregations in the next 10 years to make up for the shortfall.
