Due to the techno-industrial city, doesn't matter the ideology, or society which possesses it; it will always need many people to keep it alive, and for this reason smaller languages cannot survive in this harsh environment. Let's assume a group of people who speak a minority language with around 300 speakers, they live in a poor small village, next to it is a city where a major language is spoken, if people want to have a industrial life, they will need to move to the city, commune, whatever is more convenient for your industrialist society, and there they will stay for better life conditions.
When this happens, there are two possible outcomes:
> 1 - They won't teach their native to their children preferring them to only speak the major language, because their native language is "useless"
> 2 - They will teach their language to their children, let's assume the best case scenario and let's say they taught the most traditional form with no loanwords, only native words, and the children speaks the minority language perfectly; here is a more case by case thing, but probably this kid will only speak this language with his family, and with no one else, so many things could happen here, loanwords enter his language when talking to their parents, they start speaking more and more of the majority language with their parents, and in the future they will spread a more majority languicized version of the original language, and with each generation the language is slowly(or maybe even faster in worse scenarios) disappearing until it is finally gone. This being the best case scenario for the language.
This is the natural process for smaller languages, which are the majority of our world's languages today on the techno-industrial system by its pure nature. But now let's make a case, how could we revive this language? A fake idea of national identity could bring up many nationalists puppets who would only speak the original language in its pure version, and would force their children and relatives to only speak it; this is a similar case to Ukrainian which is a language that I know fairly well, but it also brings all the nationalist spooks, fights, racism, class division and way more stuff(evidence for this is the state of the Ukrainian language today) that all of us know so I don't think anyone here would agree in doing this as a long term solution.
So as we can see, language diversity in the techno-industrial system is impossible, maybe it can last some generations, we can even write books, make documents and such for its possible revival, but as we now have come to see, the only proper language revival that we've was for hebrew, which almost changed all the classical language, and it needed a extremely fucked up nationalist group to make it happen. Other languages revivals tries like irish, cornish, gaelic we can only see some nationalists people the effort to even try to speak it, or in some other cases nationalists organizations can bring the language to a better spot.
Here I am not saying that this is bad or good, nor saying nationalists organizations are doing a favor reviving those languages, I actually think nationalist revivals of languages have to destroy a language or a dialect for the success; let's take Ukraine as an example again, we have surzhyk, which is a mix of Ukrainian with Russian, in some cases have some really interesting vocabulary and phonology that you could argue if it was left alone maybe it could turn into a new language, who knows, but now, due to the Ukrainian nationalists, surzhyk has got a image of bad language, rural language of dumb and uneducated people; which is actually creating more divide, some surzhyk speakers are now with a strong russian identity and only speaking russian and starting to hate ukrainians, and the reverse is true with people that are stopping to speak surzhyk and only ukrainian.
So do I offer any solution? If you ask me, the only sustainable way for smaller languages to survive is through de-industrialization and de-urbanization, that's where language flourishes and develops best. This is obviously just a really personal thing, language does not have any intrinsic value, I just like it and I think the industrial system takes the freedom of personal language, and that's it.
