Come to think of it, the WTS exploited the congregational children as just another self marketing tool to show see are
JWS children are true worshiping /preachers of Christ. The same exploitation occurs in the Kingdom Halls
when children raise their hands to answer a simple question, the conductor smiles when the child answers "Jehovah God".
Or when a child gives a talk with barely the capabilities to read, impressing the audience in attendance and everyone is smiling.
