You can not have a major exodus of members every generation (born in kids) and continue to be solvent. I’m 50 years old and every new generation I seen many of them leave. Almost all the kids I grew up with left. My sister which is a little over ten years younger almost everyone in her generation she grew up with left. A percentage do come back.
When teenagers become adults most leave and yes some come back but I think less and less are coming back as time goes on. This along with the generation of those that joined in the big push pre 1975 about to die off and the cult is definitely in trouble.
Having Kingdom Halls with 200 seats yet only 40-60 publishers showing up is demoralizing so consolidating is the only way to go.
