Recruitment has all but stopped in many so-called "industrialized" countries. In the U.S. most of the growth is from children of JWs getting baptized and foreign language groups. In other parts of the world its slowing but still prospering somewhat. These countries are full of JWs who are relatively new, no recollection of 1975, the 1995 generation change, etc. so recruitment may still be viable for a time.
They need to become more mainstream to keep filling the kingdumb halls. I have a feeling that my childrens generation and definitely my grandchildren will be less inclined to become or remain JWs. For example if my kids left I would not ignore them or shun them. I doubt they'd do it to their children should they remain JWs.... the GB's psychological hold on its adherents is lessening with each successive generation. They are slowly becoming less and less credible even to people still claiming to be JWs.
