At my former hall the big money grab shocked many into donating less each month. This coupled with the realization that a new hall was NOT coming made the monthly bills hard to pay before I left.
I remember them having to do a few local needs parts on the importance of donating specifically to the local Kingdom Hall. There were months that wealthy elders had to make a sizable donation to keep their end of the bills payed.
The doubling of the monthly "forever loan" didn't help either.
