No those careers are the muscle and if they don’t they starve as they have zero value in post electric world.
As for library I can only talk about ours it is an entertaining thing with little of real value other than kids books to start reading skills. Alot of stuff is now on micro film and computer which will be useless. The micro film is mainly periodicals which for most part is useless in post electric world.
Think of the energy and resources required to keep a working age child in school instead of working on insert the blank family enterprise. Look at pre industrial revolution and think why kids where used and not schooled and what it took to make higher education that will be able to use advanced educational materials that would fit the local resources. It’s daunting and can’t be a single person or family thing that is why it’s not in our group.
We decided that it would be apprenticeships, after equivalley of grade 10 the kids would get a try at each of the main professions here and between aptitude, need of group and availability they would get assigned a 3 to 6 year apprenticeship and the master would decide when they are ready. There would be ability to cross train but doing it this way would allow for a lot of one one one time and still be worth the food required to keep them. Somethings in post electric world would require cross training ie medical would require chemistry and herbalism and farming for next Gen to be self supporting unlike now. Make and build it stronger not weaker. Also to help offset cost kids will get school in am then be assigned to working with adults. All but most young can do manual labors which will be required.
Also there will be more kids as forms of birth control will basically vanish.
It is also how much stuff from now you have built to last, building houses and such will cost tremendous effort and supplies. So now it cost cash but in future it will be alot more. Think you have an asphalt roof lasts 5 to 10 years how will you fix replace roof? New place how will you make a floor?
Yeah a metal roof twice to three times more but if you buy right kind can last 25 to 50 and some over 100 as long as no physical impacts and you can have replacement pannels. Used stuff that leaks still can be repurposed to animal shelters and barns. Costs now but compared with what it will cost later you decide.
This goes for siding, heating,washing, electric systems, tools ect one is none but crap will be soon worthless.
People ask why I bought solar pannels for$3.50 a watt instead of the $1 a watt (we distribute solar) the way the expensive ones are built and how they last. Original pannels from.the expensive company are still at 100 percent rated output after 20 years service. The cheap ones start at 90 percent and drop 5 percent per year if you are lucky. At 20 years it’s basically scrap and no buying extra pannels won’t help you as it is the solder that decays over time causing cascading failure.
But no matter what you will have to eventually trade and have others that are not of your group come to see you and provide items and skills so how do you do this ? What do you do for genetic additions to not have inbreeding of both humans and animals.
There are ways but you need to full scope plan with may fall back and contingency plans and no way you can do it alone.
