I have three girls in school here, only two of them in high school still. I wish they had been able to enter one of the high-level national schools, because they probably have one of the best overall curriculum in Argentina, good resources, good professors. This from data a couple of years old, admittedly - I knew a couple of families that had kids in school there, but I haven't kept in contact with them. The strikes are irritations, for sure, and I'm sure they may learn some things that only Argentina knows how to teach (like, for example, striking), but overall I'd say an opportunity to go to school there beats places like Lincoln if only because it's free and the education is probably on par at least.
As for Latin - anyone who speaks a language descended from Latin would be doubly-enriched by taking Latin. It's certainly no more difficult than any other second (or third, or fourth) language if you're dealing with the same (or almost the same) alphabet. Not to mention the learning that goes on about foundations of western culture and translating such people as Cicero and Caesar. People may consider it a "dead" language, but they're wrong, it lives in so many languages today and a good base in Latin provides a very strong insight into all those languages descended from Latin, including English, BTW (though English is much more corrupt in Latin terms than other, "Romance", languages).
