Does that mean the learning was in vain? I’ve probably forgotten 90% of what I learned in high school other than math. Does that mean most of my education was a waste of time?
Did the things you learn change you in some other fundamental way, that only learning those things could (ie you could come to a conclusion and forget the exact process that brought you to that conclusion, and thus the process was worth learning even though now forgotten)?
If not, then that learning must have been in vain, almost per the definition of vain, right?
Some would say separating state and school is equal or greater in importance, than separating state and church.
Yes.
And you can do that with language instruction in most cases.
Hell, maybe make language instruction more hardcore and immersive for those who need or actively seek it.
For everyone else, it's not worth pursuing 98% of the time.
