I was thinking about this recently. The Society owns all the Kingdom Halls and with desperate need of money, their closing down and selling off properties. Consolidating congregations seems to be the order of the day. The only thing that is growing within the organization seems to be the number of "anointed" ones. When I was active, there were barely 6,000 who partook, 30 years later, I read somewhere it's more like 20,000 now, and it might be more by those who partake privately.
So what if the Society decided to turn their assembly halls into mega churches. They can get rid of the smaller Kingdom Halls and have the various congregations form one big one. They'll make money on the sale of the property and make money from the donations.
