Oh dear, flipper. Now, I respect you as a long-time forum member who has a lot of good things to say, but that last post is really going too far. Imagine what an active JW would think reading this kind of Alex Jones crap. "Geez, these apostates are nuts!"
It's certainly true that the Society uses real estate to make money. The periodic ("voluntary") KH remodels are a way to keep the buildings in good shape to be sold some day. This is just common business sense and I doubt most JWs would have an issue with this since it provides more money to the Society for the preaching work (and yes, more money for further reinvestment, for further preaching work).
Some of you think that the Society exists to make money, but their initial goal was clearly just to publish literature, unless you doubt Russell's sincerity. Now, all the more since the literature ceased being sold, the Society needs income to fund all that printing. We can't deny that they produce a ton of printed material. We've seen the printeries pumping out many books a minute and we know that these millions of copies are going worldwide in hundreds of languages.
So the question here is not so much "How do they make money?", which we all agree on, but "Why do they make money, for doctrine or for the love of money?", or in other words, does the tail wag the dog? It could be that after starting out as an honest venture under Russell, eventually the divisions in charge of making money became influential over the org., but this would have happened accidentally.
If it has happened, the GB almost certainly still have as much power as they desire to have. They may choose to cede some power to Legal by checking with them on the ramifications of doctrinal changes before they make them. But Legal cannot stop the GB from making whatever changes they see fit. Can you imagine Legal telling Writing "Don't write this"? A GB member is the closest thing to God on earth for the brothers; one of them can simply walk into the Writing department and say, "Do write this", and it will be done.
If they do let Legal have their way sometimes, it's out of a desire not to upset the boat. I do believe that there is dishonesty in the way that the GB ignore what they probably recognize as valid criticisms of some teachings, and that they do this because of pride, mental laziness, and maybe fear. But we simply have no evidence that they are mere "front men", and the word of a DFed GB relative is not helpful when we don't know anything about the person and their mental state. Ray Franz was a well-known figure with unassailable earnestness, and he did not document anything nefarious about the Society, did he?
Even investing in bloodless medicine is not dishonest if it comes after a decision to ban blood for (perceived) Biblical reasons. It's just a prudent way to use insider info to earn money for the publishing work, plus investing is a means of funding something. Thus, if the friends' contributions are invested in developing a machine to help save their lives in surgery, is this not a worthy use of the money?
As I mentioned before, organizations seek to perpetuate themselves, and sometimes the Society might forget which end of the dog is in control. But belief systems perpetuate themselves, too. The belief that the end is coming soon is something that seems to be endemic to humans from all places and times. The Society could simply be seen as an embodiment of humans' eschatological phobia. It will go away when people stop being afraid of the dark.
