So think before you open your mouth.
Wow. You obviously must have done some deep thinking before blabbing your mouth speculating nonsense like that.
The WT is bent on getting every penny it can so that it can keep getting bigger and more powerful, more controlling and domineering.
By long term solvency and survival maybe you meant sustainable. If you did, Perhaps you aren't aware that one of the first things a "sustainable" business would do is try to retain talent, creative people with critical skills who are the lifeblood of the company. The WT seems hell bent on foiling followers efforts to grow their talents with the anti-higher-ed mindset.
Their mission statement is murky, changeable with every effort made to remain tax exempt throughout its lucre loving past.
Their reports of hours and publishers are doctored up, changing the stipulation for publisher reporting hours so that the totals are increased year after year. But since their requirements changed one year cannot be "fairly" compared with another and percentage of increase published. This is quite dishonest.
Likewise dishonest is their misquoting "expert" scientists, Bible scholars and academics. On one hand they say the whole world is wicked and belongs to Satan, but they dare make use of this world's "experts" when the need suits them. Dishonesty will only drive more and more followers away from their organization as they become more aware of WT practices.
So in order to hide their practices they have to keep a tight lid on "shepherding" books, elder school's curriculum and letters to elder bodies which explicitly demands information be kept secret from the rank & file witnesses.
Their public credibility, confidence, takes a dive every time their secret guidelines and dirty dealings are exposed. Case in point, the UN NGO status fiasco. There is no commitment on their part to honesty in public relations. They bend the truth and sometimes give contradicting information as part of their "warfare strategy" against anyone who dares try to hold them accountable.
As a practice they do not contract with the best available providers of services, but depend on free volunteer labor. This has resulted in much waste in the past. They repeatedly prove to be penny wise and pound foolish.
Instead of reducing waste and resources they are gluttons for printing and distributing publications that few will make any use of. Their value doesn't last a decade because their teachings change so often and as a result older publications are useless.
So maybe you didn't mean "sustainable" when you mentioned solvency and survival. Maybe you meant that they'll try to squeeze every penny they can from followers, even kids' ice cream money, to stay "solvent" and they can ensure the "survival" of their status and power. If that is the case then it makes them that much more despicable to hide their business behind a religious tax-exempt front.
Either way you meant it, they're obviously greedy and dishonest.
