Growing up, this explains my father's behavior. It can make people callous to other people's feelings, especially when they sit in on judicial committees and ruin people's lives.
This organization is facing a growing elder shortage, or just a shortage of "qualified" men as defined by stringent Watchtower standards. Anyone in an appointed position, whether elder or ministerial servant, have a heavy workload and are very overworked because of this shortage.
As time goes on, this shortage can only increase. Either the Watchtower will have to loosen its standards for qualifications (and include women in some of the work such as accounts, microphones, ect), or in coming decades, it will reach a crisis point.
