Actually they like to invest their money in land properties, and warfare technologies that gives much more money. Besides WT leaves for the goverments, other religious group that usually accuses them(specially Catholic Church)that they don't care about the spiritual wellfare of their flock!!!
Well Babylon the Great at least is building hospitals, schools, donates money for the orphans, houses for the elderly people. What really makes me mad is specially when I used to listen to JW's condemning the other Churches. I recall one day when the Orthodox Archibishop of my country said that the Church will build a new center for those who have drag problems and addiction in order to overcome their problem. Also he said that they will build a sports center for the young ones in order to keep them occupied with sports so that they will not get into drugs.
So JW's started to accuse him, so I got angry and I asked them what about WT? When did they build a hospital, or helped others? Is better to see what we are doing for others as an organization instead of accusing other religions. To critisize them is easy.
Besides WT does not have any educated people to run a non blood hospital, since they are against education. Also they prefer the "worldly hospitals" because they have the chance to say that they are persecuted from the world when it is a case of life and dead decision.
At the end of the day WT needs this wicked system in order to exist!!!
