I can understand what you are saying and till a few months back I would have agreed worh every bit of what you said. But here's where the problem starts with ultra orthodox traditionalist society.
As everything is dictated by the book , you follow it to the letter and become stagnant in the time the book was written. Simply look at the example of Europe and middle east. Both started off as different sect of same judeo Christian ideology and both lived in dark ages, al though under Ottoman Muslim world was somewhat prospering but the rest especially the gulf Arab tribes were all shit flinging sand niggers. But Europe had revolution, protestant revolution, followed by Gutenberg than industrial revolution. This propelled them to be such power which ended up dominating the whole world. At the end of the day 100% literacy where people spend more time fixing present and preparing for future than reading and reciting old books won.
Now you'll say well we can have traditionalist society and 100% literacy as well.
To that I say BIG ASSS NO. You can't. traditional society is maintained by an authority. An authority where a limited number of individual wield power. If everyone is capable of wielding the power what reason is there to not only question but topple the authority as it suits me.
Just look at it this way. Vast majority scientists, engineers, entrepreneurs are from Western Europe, America and even Israel (where orthodox jews don't hold much political power). Even Japan, Korea, Taiwan is an open society. China is an open market, the authority had to give up the pillar of economy to pull it's people out of starvation. So yeah your society will live and die with the cope of religion without hardly ever competing with the world let alone beat them to a space race. Certainly this will result in the economy being weaker than your more progressive counterparts. And finally the steadiness will translate to sluggisness among your people. With no war and no capability to mount a full fledged war, your young adult will be spending their daus writing poetries and finding their best fit suitors.
The best idea is to have countries like America. Where males are educated and trained in the technical and technical studies only. no humanities bull shit. they come back home open up their iwn entrepreneurial venture or be employed in an.existing one. But not let the degeneracy of the west to.be brought back by the sons.
