Whether the WTBTS survives another 5,10, or 20 years is open to lots of debate and disagreements, but one thing I'm convinced of is this, they have not revolutionised their money-making cult because of greed, but because of desperate need! The corporation hit the financial buffers with such speed and impact that it shattered numerous "sacred" pillars and structures at Brooklyn. (cause/s open to speculation - but still unknown)
Unless any evidence to the contrary can be shown, the org has never been so financially secure in its history! Streamlining the corporation's global structure, overheads, expenditures, and crucially, morphing into an electronic religion, has apparently secured their finances & future for quite some time to come. However, the continued contraction of the org and its constant begging for money leads a person to conclude that money pouring into the WTBTS is seriously haemorrhaging out. (see latest plea in study article of January 2018 WT)
Just my (optimistic) 2 cents worth. Whatever the case, it's all good news for those who have woken up.
