I have noticed that many of these large churches offer so much more to their congregants than the Watchtower does. For example, there is a large church in the community where I live that has free day care for parents who are attending Sunday services.
A curious variation on this theme was what Doctor Gene Scott did in his downtown LA Church of AOG (Assemblies of God). Doctor Scott had decided that young children would disturb services one way or another: crying, mothers getting up in rows stepping on/over people to get tot he aisles and then trundling down the aisles to restrooms.
(My mother recounted that, as an infant, I liked the sound of breaking glass and would throw my milk bottles in the aisle to listen to them break.)
So, children under 12 are not permitted in the main hall for services. They are kept in an "day-care center" area; but they aren't kept there for long. Volunteer adults are with them. Then they all shortly get on chartered busses and visit local museums or other attractions. Scott said that there were 20 or so of those features within 15-30 minutes of the church itself.
The children are taught/told that it is a "privilege" to attend the Church services. But they enjoy themselves and are learning in the "day-care center" environment.
So when they are 12 years old, they are allowed access to the main hall. But they don't get to sit wherever they like, especially with their buddies or friends of the opposite sex. They must SIT WITH THEIR PARENTS!!!
I don't know if Dr. Scott's methods are still in force; somewhat after his death, his widow, the new "Pastor", has made changes. They obviously are after money and that may have declined; she has greatly curtailed the local area TV coverage.
