In a comment Ram wrote, “What are your thoughts on governments (or quasi government bodies) deciding what subjects should be taught in schools. For physical and social sciences, yes, I could think of market deciding it. But specifically what about languages? Can a government decide? But again, if we leave it to the market, some languages may not survive. I find it abhorrent that in some Indian states one could complete schooling all the way until Grade 12 without learning the local language.”
TL;DR version: Government should never get into any aspect of education — funding and running schools, dictating content, etc. That’s the job of parents, and if necessary, the job of society. Regarding languages, people decide what survives and what doesn’t. It’s a pity when a language dies but the use of force to keep a dying language alive cannot be morally justified.
