The society is a corporation and all decisions, and I mean ALL decisions are made for the continuing existence of the corporation.
It only makes sense for them to do this. Migrating to a less personal and easily accessible format via the internet broadcast, they can consolidate the multitude of locations into a "mega-church" type meeting place. No boxes of literature to handle, fewer qualified men needed to oversee. The individual has never been important to the WT corporation. They will come up with more inventive and easier ways to "count time" to keep their reported numbers up. All they care about is how they look on paper to the clueless faithful. If the ministry numbers remain strong and increasing (through creative accounting), then the changes have jah's blessing.
I live in so cal, Long Beach area. All the congregations, and there are a lot of them, are still functioning. My old hall is in a old former church built in the 1920's. It is smack dab in a neighborhood with stacked parking and limited street parking. It houses English, Spanish and Cambodian congregations. It is a terrible location and the neighbors hate us for taking up the street parking in front of their homes. I think the elders there would welcome an amalgamation of the congregations.
