When I was young, the COs were motivated by 100% conviction. They provided their own car and usually a trailer. Received almost nothing from the bOrg, and little from the circuit. They worked every day and every night in their assignments. Assemblies were a ton of work for everyone, especially the CO. They earned respect and expected little. They worked diligently and urgently since the end was sooooooo close.
Now, the COs are corporate middle managers. Company car, all expenses (sometimes very questionable) paid by the congregations of circuit, additional reimbursement from the bOrg, circuit apartment free and clear. Set schedule for free Mondays, minimal weekend activity, late mornings, more free evenings. Congregations to provide all food and additional housing. Most work delegated. Almost no original material, use formulaic corporate outlines over and over. 'Motivate' by stressing more field service or alternative witnessing or phone witnessing or more RVs. Expect everything, earn nothing, since you are to be respected for the position you are in, not for anything you actually have done. Tell everyone the end is soooooo close, but don't bother making friends since you'll only be in that circuit for 3 years and then on to the next. Kiss the @sses of the upper management above you, brutalize the workers below you--that's the formula for a successful middle manager.
Today, most of those that would make good COs are the substitute COs who work for nothing. The current crop of COs are company men. The CO training school at Patterson actually seems to made them worse. Now their attitude is, "It's all about the numbers!"
