I inferred this from the paragraph.
What if, Slim, the "decline" in membership is deliberate and wanted by the powers who be? What if the org has decided that it is best to pare down and get rid of those who aren't loyal (true believers only) and those who will donate more more money ( true rich believers only need apply)?
I can see that what follows is an argument for WT promoting in third world countries. Which I don't see actually. (Why stop sending new Gilead missionaries and close down branches?) I think JWs are growing in third world countries for the more commonly cited reasons (lack of Internet access, education, low income, despair, more religious societies) rather than a result of a GB master plan.
