I have been reading a lot about the downsizing of branch offices and congregations lately. I know of a few being downsized personally. This addresses two critical issues that the GB is facing
One is cash flow. A real consequence of dumbing down their flock is, they are usually not formally educated to get work that pays well. As a result, donations are on the decline. Additionally, recent converts (at least anecdotally to me) are not in as well educated demographic, meaning their ability to make substantial donations is limited. People who have higher paying jobs also have better internet access, and some curiosity, so they can see what JW's are about on their own, whereas 20 years ago, that wasn't the case.
The other issue is the drop in elders and MS. We all have seen it. You can't have congregations run with the amount of elders and MS that are available. This will also limit the amount of CO's needed to visit the congregations, so the Borg saves money there as well.
The GB will spin this as using "YHWH;s" extorted/donated resources more wisely. In fact, the GB just wants to make sure they are taken care of. The next 20 years? That's GB 3.0's problem.
