My experience with JWs is similar to the other posters here. I especially get the impression that for most of the younger 2nd / 3rd gen JWs it very much is basically a social club and the "end is nigh" concept isn't really of much interest.
I recall back in the 70's it really was so different , with all the "stay alive till '75" encouragement.
I remember a few years ago a ( former ) very good friend of mine who is an elder JW bought himself a second home and was taking about it as his "pension plan" ( he was about 40 at the time ). His wife is a pioneer & he is the kind of higher up elder who always gives talks at assemblies etc.
I chatted with him later alone over a few drinks ( at that time I was planning my exit & he knew I had doubts ) & asked him about why he described it as a pension plan bearing in mind that it would be 25 years before he retired. He just shrugged his shoulders and admitted that he no longer believed that the end was coming , although he said his wife did. He had no pension plan at all & he had seen many older JWs really struggle in their later years , including his own parents.
I suspect many JWs , consciously or sub consciously , are like this. While they might pay lip service to it, in their hearts they know it might never happen , so they live their lives accordingly.
