It certainly feels like its imploding at the moment doesnt it! From closure of bethel homes to STUPID doctrine changes, it appears that money is becoming a problem and people are no longer satisfied with what they are being taught. In my congregation, i know of several brothers who werent exactly too happy with the new light that was coming from the GB. Not only that so many of them (including my dad and brother) have become so disgruntled with the silly, nit picky little rules that they just want out of such pressure. When they realise that life is so much easier when you dont go anymore its such an eye opener.
Of course there will always be the die hards, but i wonder if they will still be there in 20 years time. When they have gone I cant imagine who will be left. It appears to me from the figures that the preaching work has stagnated. From awareness in the media and personal experiences, people just dont want to go anywhere near JWs in this country anymore, brandishing them as wierdos. Eventualy the numbers will die down and the GB will have to realise that is happening and do something different.
I think the WT business will always survive though as it has shares in some of the worlds major businesses, but as an organisation im confident that sometime in the future, it will all go down the pan and then we will have to help console those who no longer have anywhere to go.
