Thank you for sharing. We have seen a few of these reports recently and it is a very interesting look at what is starting to happen within. It seems that some are falling out of love with the Watchtower. It may be that they still believe she is "the Truth" and "God's Organization" but they are responding in subtle ways, such as by not reaching out, witholding donations, or skirting some of the rules. Take a look at the chatter coming down from the leadership. They gnash their teeth at how some of the old timers are actually encouraging younger ones not to make the same mistakes they did and prepare for a future by going to college. In response the leadership grows more controlling, more hardline and orders that any elder who has a child in college will have to be critically looked at to see if they are still able to serve in the congregation. These orders come down and the elders become even more disenchanted at the clamping down and respond by withdrawing and stepping aside, shrinking the pool of elders in an organization that is already starved for local leadership.
I expect this trend to continue, even growing as we approach 2014. The "stay alive 'til '75" generation are approaching retirement and with no end in sight they are facing the reality that they will be dying in this system of things. They may be looking at the life they gave in kingdom service , the sacrifices they have made, and see it as futile. They have no retirement to speak of and are facing the challenge of making ends meet. They are looking back sadly at the family they have missed out on. (Those that have lost family due to disfellowshipping or have chosen not to have family until the Paradise.)
I think it will be my generation - the post 1975 crowd that offers the best hope of keeping the Organization afloat in the near future, though in many ways we were already less zealous than our parents. We missed the hype of 1975 and were too young to appreciate the significance of 1994. Those of this generation that remained in it still believe it's "God's organization" but on some level have lost apocalyptic certainty of those before them. They lived through a time where the leadership's stance on college was much more moderate and thus have a more balanced outlook toward the world outside of the religion. These are the ones most likely to insist their children go to college despite what the Organization rules. While they would hope the end will come they may have already planned on living it out.
The current generation, including teenagers and those in their early twenties, is going to be a major loss. They are decidely more worldy in attitude, outlook, and action. As the OP mentioned they are leading "double lives". These ones really skirt the rules; they maintain association with disfellowshipped ones. They are nominally JW's but not much interested in reaching out to serve and even if they wanted to they lack the qualifications. Many will have already been in some judicial trouble and if they remain they are working off the stigma of that.
The Organization will not be able to survive its current form passed thirty-five years. I'm not saying that if will totally die-off but it will be a radically different beast. The attrition has already started. The Watchtower is losing the hearts and minds of her followers. The Governing Body is responding by becoming more hardline, which I believe will cause spot-fires of rebellion. This has already started in the minds of the rank and file but will blossom as we move ahead.
