TL; DR: There is nothing new under the sun. What the luddites of today fear, has been proved wrong every time there was any advance in efficiency since the dawn of mankind. Now we even have a huge reserve of pent-up production capacity, because most of the people of today are just working in the system doing nothing of value. With the release of these people, the future looks brighter than most of us can even imagine.
What type of production capacity? Are you talking about manufacturing?
Manufacturing is never going to come back.
Its replaced by our tech with machines, and other assembly stuff is done with china. The more things you see automated, the more jobs are cut like those cashier people.
Look around you!
How many hours per week do the people in the system professions actually work? I mean spend time on doing something, anything, that makes the fellow humans' life easier. Agriculture does, manufacturing does, distribution of goods does, many but not even close to all services do.
How much of your time do you spend on doing anything meaningful? I spend exactly none. All my time is consummated in getting the word out that there IS a life worth living out there, and the problems of the world are non-problems - the symptoms of a cancer that is far bigger already than the whole of your natural system! Multiple times bigger.
I have grown to see that there is no easy way to dethrone the current masters. Even keeping yourself out of becoming their slave is reeaally difficult, and getting anyone to reject them is even more so. The methods that would be needed to dethrone them are prone to lead to the "meet the new master, he is the same as the old master" situation.
My understanding is that Jesus is coming soon. He promised. The millennial kingdom, "paradise on earth", is the first time in history achievable with the technology we already have, so despite that destroying the kosmos ("world", the slave-market of Satan led by the people who call themselves Jews, controlling the Hollywood, banks, and media nearly worldwide, and having infiltrated many governments such as the USA so that there is scarcely any American voice in any major decision).
What I see necessary to understand are:
1) The kosmos=world is currently the domain of Satan (this was verified by Christ under temptations);
2) The Christians are instructed to keep away from the world, which may not always be easy nor free, but worth it, since I havent found any Christian who believes the world's lies yet has a testimony that the Father approves. You can't stick all your senses to shit for decades and expect that your speech and conduct would be not shit as the result. They will be shit.
3) Since Jesus already achieved the victory on the cross, we are empowered, capable and tasked to spread the Gospel of the Kingdom (including both salvation and that stuff, but also that the kosmos is judged and will be finished physically as well, and the leaders of it physically thrown to the lake of fire (hell) where their instigator, Satan, also is)
4) The manifestation of the Kingdom coincides with Jesus' coming: he is coming with all his saints, so if we are martyred during our struggle, the killers will be in for a nasty surprise.
5) The practical change in the natural laws will be that evil is very much contained during the time that Satan is in the pit. I think this does not need to manifest itself in anything more than all the people understand what I already do, and consequently mind their own business instead of attacking each other and causing damage (in all levels of life from stealing of your lunch money to the domino destroying of entire countries in Serbia-Iraq-Libya-Ukraine). Especially as such a wonderful and interesting place is rules by our Lord Jesus Christ himself, and we already know his ruling style never involves force.
6) The unfathomable increase in production (of everything, mainly services since we already have too much of most goods) is made possible by eliminating the negative production of regulations, war, propaganda, unemployment etc. There you only need to work 4 years to earn for the rest of your life, and of course you quit school (even if it was offered and free) since it does not pay off to study 20 years for a 4 year career. As a result, the slavery which currently is on average more than 50 years, is shrunk to beneficial, productive and interesting work of a few years.
