I think the comments from LongHairGal and DATA-DOG are right on. This is exactly where this is all leading. What I don't know is precisely what the income to the branch offices and HQ is being used for. While it is true that there is some construction cost to the Warwick/Tuxedo project, that is a small expenditure compared to the income generated from the sale of property in New York. The only costs there are for material, a small bit of contracted work, and property/permits. Everything else is a massive amount of volunteer labor - and the volunteers have to get themselves there and back with no expense relief except for (maybe) room and board (not sure if this covers everyone who comes from RBC to help).
The actual contributions that come in for congregations is fairly miniscule and comes from a small number of congregation members. However, at circuit and district/international events, the contributions are more significant. While at circuit events the donations are directly remitted to the assembly hall or venue rented with some donations going to Worldwide Work, for district conventions all contributions are remitted to the branch office and the branch office handles venue expenses directly. A rough back of the napkin calculation for district conventions in the US would yield roughly $12m after venue expenses so the income from those is not as much as you'd think. The large proceeds from the real estate sold might approach $1b, but I suspect that this is a hedge against drastically dropping Worldwide Work contributions - which are about a 1/4 of what they were 20 years ago. Investing those funds won't gain them much but the run time will be significant in the face of drastically reduced income.
In the end, if we expect the organization to provide general relief when the next big financial collapse occurs, I think their direction from them is going to be that the few employed people share everything with everyone. And that is going to be extremely difficult for most folks to do. Very difficult.
