Did you notice what was said at the 14:15 mark;
Adult recruitment are more of a bonus than a necessity for major religions who are guarantee a steady influx of child recruits
This gives us the reason why the WT is not to concern about new adults members coming into the organization or why they don’t give a hoot when adult members leave the organization.
The “Child Recruits” are what is keeping the Organization’s head above water. These young children who are baptized at 6 to 16 years of age will finance the Organization for the next 30 years before they wake up. Once they wake up to ttatt, who cares if they leave and get disfellowshipped, a new batch of “Child Recruits” is on the way.
According to the video, adult recruitment is a bonus but not necessary for the WT Organization to thrive, Child Recruits is what keeps them going.
