The first time that I heard about worldly consultants was in relation to the printing paper. This is something that I learned thru the grapevine and if is not correct there are tons of ex Bethelites here to correct me.
I was told that the WT was in the habit of taking advantage of low cost offers for printing paper and buying tremendous amounts of the product, when consultants came in trying to improve their operation they called to their attention:
Capital that was invested with no return in the paper.
Spoilage, sometimes the paper reams were spoiled after many months of storage.
Space, there was a need of storage room for the paper.
The suggestion was to just buy enough paper for a short period of time and use the resources for something else.
Like I said maybe truth or maybe urban legend, if truth shows that the motivation was in this particular instance $$$$$.
