Hi metatron,
You have to remember what attracted most people to the society in the first place. For many they were under achievers and mostly without much ambition.
The JW org fitted in very well with their take on life. The org will do just about everything for you. You don't have to think or work out much yourself.
So those rank and file really want that situation to continue. The society tell them bad things are hapopening in the world, and hey they are right. It matters not that most things are better, the society and the sheep only look at the bad things. The rank and file are told they will be persecuted and hey they are. Even if it is something as trivial as going to a birthday party. If we ask them why not they can't go, they view that as persecution.
So I am afraid things need to get a lot worse in the org. before most of them will start to ask questions. When all said and done they are still seeing some increase and that will hold a lot of them in. Most of the other things will be put down to restructuring, which other organisations are doing as well.
The uni and college thing has been going on for years. All witnesses know that it could take them out of 'the truth' so as far as they are concerned the society is right to warn them about it.
I know it's depressing , but let's hope things do get a lot worse for them in the near future, and we can get our friends and family back who have been caught by this false religion.
