the Wacktower is simply a large corporation that maintains a profit margin. As crude oil goes up, so will the costs of printing wacktowers and books. Sooner or later drastic measures will be taken to reduce costs. We have already seen some of these measures and here are some more possiblities
1 hard cover books are now soft cover books
2 re-studying of the same books over and over
3 elimination of entire meetings (book study)
4 downloading the Wacktower from the internet(PDF's)(thanks to fokyc that is basically a reality right now!!!)
5 Audio & visual links to assemblies (they already have audio links for meetings)
6 Online preaching work (you can talk to a real dub online to get the troot)
Anymore things the Wacktower could do to reduce costs?
