I took Latin in high school and felt that I wasted four years I could have spent learning (rudimentary) Spanish, or at least something that had any cultural relevance at all. You have to find a way to make kids care about it as well as justifying its utility.
I see Latin and Greek education as historical relics, akin to how we used to emphasizing testing students' ability to construct shapes with compasses and straightedges, or their ability to memorize bible verses.
My high school was heavily focused on Latin and ancient Greek. We spent the first two years grokking grammar and semantics. Then, in liceo (the last 3 years) we would study history by translating and studying poems, speeches, plays...
Teacher and students used to discuss for hours about the meaning and context of this or that sentence. It was a wonderful way to understand our ancestors' mindset. Dead languages are the best tools for a deeper appreciation of history.
German has specific prepositions I recognize as equivalent to each main Greek preposition as defined in that chart, except maybe the distinction between εις and εν, which German would handle by a noun case distinction (ancient Greek εις την θαλασσαν → German ins Meer (accusative, < "in das"), ancient Greek εν τῃ θαλασσῃ → German im Meer (ablative, < "in dem"). German breaks up some meanings differently -- "among" is unter (shared with "beneath" rather than "between") -- but anyway there are other languages with a pretty nice set of prepositions!
Picking up latin as an italian seems far simpler (and probably more useful) than as an english, as you can guess large part of the lexicon and you will be exposed to "volgare" (transitional latin-italian) when studying early italian literature.
But would studying Old English be of any use for italians? I am not sure.
The United States is largely monolingual in English for a thousand miles, and the language ideology here causes immigrants to want their children to shift to English monolingualism as quickly as possible. And thus bad Latin is more useful than bad German.
I've visited Mexico with my Spanish-speaking wife (semi-natively) and while the locals loved to hear her speak their language, we communicated mostly in English if we wanted to be easily understood.
The struggle is real for Americans, or for native English speakers as a whole. For Americans, there is no other language spoken for thousands of miles like you mentioned (Mexico and Quebec (to a limited extent)), and even then, most of the people we interact with on vacation will speak English.
I put serious effort into maintain my German, and she puts serious effort into maintaining her Spanish. But we rarely have the chance to actually use it, even if we're in a country that speaks the language. English has won.
I have been learning Chinese in China for about 7 months, and have a functional command of most conversations because I never ever use English during those conversations. English will always win if you keep biking with the training wheels on.
When I lived in Cambodia for an even longer time I didnt learn nearly as much Khmer because I was constantly speaking in English, even though I diligently listened to Khmer conversations and researched the language. Like programming, language learning is much slower as a spectator sport.
In my travels, I've yet to run into someone who I really need to talk to who only speaks their native (non-English) language.
And feel free to drop me a mail and have a call if you want. :)
There's this common argument that prescribes utility to studying Latin via the value you gain by understanding biological, legal, and religious terminology.
I think that the net utility that you gain through this mechanism is approximately zero. Or rather, the net utility over other, more direct methods of acquiring this knowledge is zero. I think you could gain the requisite understanding of Latin to gain 99% of this utility in a few weeks of study, and that if understanding these roots is so important it should be material in our English classes, not in a long-term study of the Latin language itself.
Besides the "it helps you to know roots" argument, the study of a language gains utility largely in being able to speak the language, make do when traveling to places where the language is spoken, or consume the literature and media in the language. Moreover, the utility you gain from the language increases exponentially - a year of (half-assed, high-school-level) study is pretty useless, but after a few years of it, especially with higher (college-level?) standards, it's immensely useful because it opens you up to whole new worlds.
I think the best argument for teaching languages in high school is that this exponential growth starts earlier and is more likely to ever happen (especially for people who don't go to college or don't study languages there) if we start earlier.
Granted, there's utility gained from appreciating the culture of the language even as you learn the beginnings of it in high school, but I think that's dwarfed by the long-term potential for useful bilingualism and having the ability to more more easily experience new cultures.

also, anecdotally, my bad Latin has given me essentially 0 utility in my entire life since high school. Perhaps I got a few novelty realizations here and there, like identifying that "tractor" came from "trahere" and "et" means "and" in "et cetera", but those are trivial. Maybe my experience was unusual and others gained more from it. Also, admittedly, I can't really quantify or remember whether it improved my SAT scores or whatnot, but my overall assessment is that my Latin study was negligible.
Arguably, you could say that about many bodies of knowledge as much as Latin. The question is really: What percentage of people take that mandatory one year minimum of high school language and really build it into something valuable? I think it's pretty low. And,
bad German < bad Latin < good Latin < good German
U.S. school systems generally are simply unwilling to invest the resources needed to get kids really bilingual.
I do think that if all language programs are bad at a school then bad-Spanish would still have a higher utility than bad-Latin.
I actually got to do lots of creative problem solving somehow, but I understand how many did not. Coding is where that really took off but I did math contests and stuff when I was younger.
Dead languages like Latin and Old Greek don't add lives. You don't even speak them.
More seriously: I'm all for offering Latin, Greek, and even Esperanto but why would you give up teaching modern foreign languages? Why do you think they'd get a lot more from a year of Latin or Esperanto?
I took four years of high school French, and got decent grades. I recently started reviewing and learning more through flashcards in Anki. On the one hand, the fours years of "study" put enough French in my head that I'm making progress this way... on the other hand, as I continue making what is frankly a great deal more progress with the spaced-repitition than I ever made in school I still can't help but notice I still can not fluently read much of anything, let alone speak or hear it.
Now, as it is common on the Internet to confuse saying something is true with advocating for that fact, let me say that A: I still think learning a language is a good idea, I just don't think what we have now can actually be called "learning a language" and B: if we were ever allowed to change The Holy Curriculum [1], there's probably more effective ways to teach a foreign language. I can't help but notice that my Anki-based studies are wildly more effective than what I tried to do in school. (They're also still inadequate on their own so far. No contradiction there... my schooling was even more inadequate, you see.) Four years of a properly-researched and developed language program, with proper software support, might have produced someone at least capable of using the language at the end.
[1]: A phrase I am settling in on to indicate my contempt for the idea that we need to deeply reform education, but we must do so under the constraint that nobody is ever allowed to remove, add, reorder, or change anything we do, ever.
1) My parents and I recently took my 5 year old nephew with us on vacation to DC. He tends to sing at that age. We were in an elevator and he started in on a song and a couple from Spain started asking me questions about it. I really could only say he was being taught Spanish at his school.
2) I just cannot do a guttural with my voice. It sounds like I'm coughing. I have such a low voice anyway that it sounds wrong all the way around. At least I learned from a male instructor, that's a bit important as the sexes speak differently in Dakota. My old boss, a female, learned to speak from her uncles and her aunts thought she "spoke like a man".
3) I still do server names in Dakota. wanca is my #1 server.
The dual-language immersion programs are really awesome; I've seen kids from monolingual English families learn to do all their math work in Spanish by the end of kindergarten. Teaching kids language in that way is so much more effective, I hope those programs only become more popular.
They won't be speaking Latin either, but at least some written knowledge of Latin will be useful. The basic paradigm of classroom language education started when Latin was commonly taught... and since it focused on teaching passive, literary use of the language (rather than active, oral use), that was entirely appropriate.
But superficial, passive, literary understanding of modern national languages doesn't help anyone much more than it would of Latin.
A superficial literary understanding of Latin gives you middle class bragging rights and a substantial step towards being able to parse the original text of a literature which has been exhaustively translated into English, complete with notes on shades of meaning. (And an even more limited grasp of some of the fundamentals of Spanish, I suppose) And since the source material is all ancient texts, you can't even pep the teaching up with some relevant and modern material or motivate the students by the prospect they can use it to backpack in Peru or do language exchange in Madrid.
I'm not persuaded that the inadequacy of languages teaching is an argument for the same time to be devoted to devoted to something which is even further removed from being useful and the teacher is even less likely to be adequately equipped to teach.
Latin may not be a living language, but it remains very widely used in scientific terminology, law, religion, and elsewhere. Like the prestigious national languages, it is a mark of erudition and social status; the demonstration of which is itself a purpose of education.
The supposed economic value from learning modern national languages is wildly overstated, for English monolinguals. It's better to learn languages because learning languages is valuable for its own sake, and pick the language you learn simply because you like it.
There is a huge disconnect between our implicit goals for language learning in this country and the effort we expend upon it.
I strongly believe in the value of language education, but given the amount of time and money we're willing to spend on it, we'd get as much or more benefit from making them study Latin.
With Latin, all the people who want to learn a Romance language would get a leg up on it, and all the people who want to study biology would get a leg up on that, and people who are fine with just speaking English will get more insight into their own language.
What's wildly overstated is the benefit learning Latin has on anything other than taking the SAT. Studying French is much more beneficial to speaking French than studying Latin and I shouldn't have to explain why that is the case.
If you buy the critical period hypothesis anyway, which I do not.
The "mandatory one year of foreign language in high school" is a relic of decades past when Latin and Greek were widely taught, and that is what they are mostly what they are suited for. It is just as much a relic as Latin is.
There's nothing on the scale of full-time immersion, nor is there likely to be, but there's now a small minority of Latin teachers who are presenting Latin as a spoken language, including using Latin as the language of instruction and attempting to apply modern language pedagogical techniques like Total Physical Response. So even some Latin teachers might agree with your criticism of the less-holistic teaching styles and the distance they put between students and the language.
Edit: I didn't notice that you were also advocating teaching Latin further up in the thread.
Let's be honest here - nothing of value is lost.
The opportunity costs of even one year of any non-English language for American HS students makes it simply not worth it.
Why teach Latin, Greek, or Esperanto badly? How does that help?
And if you can solve the "badly" problem, why not teach something that can be used day-to-day?
The "badly" problem is actually a really huge one.
There are large cognitive benefits to bi- and multilingualism, but for these it doesn't actually matter what language you speak: a heritage or minority language is as good as anything else.
But the classroom model of the United States isn't actually designed to make people multilingual; if anything, it's the opposite. The default language policy of the United States is mostly to shift people to English monolingualism, no matter their circumstances, heritage, or language rights.
But these utilities really don't justify the classes and resources on their own... If we want high school to produce the greatest amount of utilons, we should be explicit about that, but then many many things will need to change. I believe English should be the world language, there's no practical reason to teach anything else at the expense of other more practical things to teach (like programming), especially in English speaking countries. If we want high school to more approximate what Universities used to represent, such as encouraging more Intellectualism (which I don't think is all that great, at least society-wide, from a utility perspective...), we should be explicit about that too, and again things will change. You might want to have students study French, Greek, Latin, Lojban, etc. for at least 2 years each because of Intellectualism -- but you may also want to balance that with more modern things like deeper computer science or math or physics, which won't help most people in their future lives either but can at least be fun and intellectually interesting for people who want their Intellectualism a certain way. Or we can try for a mix, but I'd propose that our current system is a mix, and other mixes will inevitably resemble the current system by being one-size-fits-all and not work too well. So if we want both, separate. Bring back trade schools and let young teenagers wholly uninterested in purely intellectual pursuits get to doing more interesting things like building a house or building JavaEE applications, and let the intellectuals do their thing without constantly having to waste time and energy rationalizing some vague utility and relevance to their proof-carrying code research.
If all you're going to do is make high schoolers take a year of foreign language in a classroom, they'd get a lot more from a year of Latin or Esperanto.
Edit: The Klingon Duolingo course should be pretty awesome, though.
