Jehovah's Witnesses attend 3 meetings per week,hold Bible Studies(yeah right),go out in service (paying for their own gas),attend Conventions(at their expense),purchase literature from the WTS and each congregation have Elders that handle all the discipline in the congregations.
So, besides printing a book here and there,cutting down the Awake and splitting the Watchtower in two,and planning the dull and lifeless Conventions,isn't all the work really being done by it's members?
