The watchtower never provided emergency food that had a long storage life. Everything had to be refrigerated after opening and would still expire shortly thereafter. The problem is all of their "food" (in due season?) has expired and is now unsafe for consumption.
Back in the 60's and 70's they still had the "generation" due date. That expired and they took it out of the old cans and put it in newer cans to make it look safe.
At this point I think all of religion is just Grown Up Santa Claus. But the false JW idea is worse than the false concept of dying and going to heaven. Most religions have the best of both worlds. You live your life and then you die and go to a better place. At least they had the dying part right. Knowing for a certainty that you are going to die in your 70's or 80's kept the idea in mind that if there is something you want to do you had better do it. But being told that there is a catastrophe awaiting that you must keep in mind so that you survive it, keeps you in a state where you fall victim to putting your life on hold. That would be fine if something REALLY happened but if you have been a JW for 63 years like I have (3rd generation), you burried a lot of sincere relatives that squandered their life and their children's economic security for nothing.
A lot of people that became JW's after they were adults don't appreciate the deep disappointment of those who were raised to believe that they and their parents and grandparents weren't going to die. At the deepest part of our brain is a paradigm of profound sadness that is worse than a hell where you could be tortured in the presence of other people who had the satisfaction of knowing they chose their path. Dante couldn't have thought up anything like it.
