I see this not so much as elite born-ins but the common person (in every country) who was raised in a Christen household where it was a part of life and death that you pass on to a better place.
I think you're right in that the large increases in jw numbers are coming from African, traditionally Catholic countries like Angola; where rejecting the emblems would be difficult for New converts.
However, Dark Spliver's kchart shows that anointed numbers in the UK decreased at a faster, and notably steady, rate than in the USA where the real JW elite reside.
This very much plays in with Orphan Crow's theory that it's those from the more prominent jw families, perhaps living closer to the centre of power. So in the USA those new anointed were replacing the dying ones despite the 1935 closing date.
And now that's old light, even more are quaffing the Holy juice if it gives them a shot at being the ' new Moses'
