I agree MS, as has been debated on many a thread, they have to get out of the 1914 thing somehow, I think the safest route for them is natural atrophy, and they are trying to reverse slowly, and litigation free, out of the Blood Doctrine.
The paradise earth is the carrot on a stick they dare not drop, and the classes of believers is integral to their rigid control of mind and money.
As we have seen in recent years the Doctrine of the FDS class is morphing so that the GB only, not the other partakers, become synonymous with the "FDS", so we are fast getting three classes, the parable will be due for another mauling to prove this to Dubs who will lap it up as wonderful "Noo Lite".
I think for you younger guys the change is not as dramatic as what I have seen in my lifetime, the religion I was born in to in 1950 bears only a passing resemblance to the Watchtower "Worship the Governing Body" Cult of today.
