Great point about the Kingdom melodies: they, like the reading materials themselves, are pablum: bland, utilitarian, one-size-fits-all-so-do-you-think-you're-special?
No worries about chaos in NSOT: just like how the miraculous events depicted in the Bible are explained away with those 3 easy words ("God did it!"), ALL difficult issues in the NS will be solved by changing the tense, eg "God will do it"! World's energy problems? God will handle it, unlike stoopid (sic) unworthy mortal men, who tried doing it on their own and failed, making such a mess of it that had to step in as if to say, "you're doing it wrong! Stand aside!"). Leave the hounds of Armageddon....
There will be no need for engineers, designers, or any skills except for what is already encouraged: skills like carpenters, plumbers, electricians, etc. If you remember, there was a wt many years ago that specifically stated that these trades are GOOD PRACTICE for the skills needed in the New System, so why not learn them now? Oh, lots of clean-up skills needed: I know some JWs who helped clear debris post-Katrina, seeing it as good practice for Post-Armageddon (since the skills of cleaning an empty office don't QUITE simulate that). Bring a Saws-All!
None of which requires critical thinking skills, but just the ability to follow simple, detailed technician-level instructions (the same basic skill needed by enlisted members of the military when entering; the officers and NCOs are the ones who are eventually trained to be the leaders, not the privates).
