A point I keep coming back to is how little sense it makes to have a free labor pool involved in activities that don't contribute to the bottom line. It just doesn't make sense from a business perspective. I imagine that if a consultant were hired one of the first recommendations would be to mobilize the labor force in a way that contributes monetarily to the group.
The door to door work used to be profitable. I don't believe it's been profitable for at least 25 years and we're seeing the consequences of that namely less and more cheaply-made literature. I keep looking for signs that suggest the WT will go all-in on the real estate business. Encourage their members to donate their labor to construct buildings, use the buildings for a while, sell them for profit (since the WT only paid for materials), build new buildings, rinse and repeat. I believe we're already beginning to see this shift.
