I wonder if they tithe 10% on all their freebees.
Hirelings
Godzilla did you forget rest of the story...
Once upon a time over the life of each president they have walked the walk of each calling they received and in their life time and paid more than 10% tithing in their secular earning years and still are paying more than 10% in their tithing in their twilight years.
So the Church provides their president a home where dignitaries etc. are received from all around the world as well one needs to feed those guess so they receive a meal allowance.
The modest stipend the GA receives they also include in their tithe paying.
