Sterile clones with selective memory wiped. The clones must be 100% obedient to the "prince" elders as to their scheduled work assignment, living assignment, etc.

If we cooperate with those taking the lead today, perhaps finding contentment and joy in new assignments of service, we are likely to have the same attitude in the new world ... Today, of course, we do not know where each one of us may be assigned to live in the new system of things. However, cooperation will bring us contentment and great happiness as we do Jehovah’s will wherever we live on earth at that time.
