In my home country (Italy) the "usefulness" of teaching Latin in non-technical schools (i.e. High School, basically) has been debated for at least one century now.

I do not regret having studied it, especially because I had good grades with little effort, but I came to the conclusion that yeah, maybe it would be better to devote more hours to general purpose stuff (think logic, statistics, basic accountancy and and stuff like https://en.wikipedia.org/wiki/Thinking,_Fast_and_Slow) which would probably be more useful for people who need to operate in modern society.

If you really want to study Latin or Greek (or anything like that) you can do it as a hobby, or choose a University track that includes those. But as an average citizen I think that an understanding of the numbers published by media, or the ability to manage your own budget with a spreadsheet would be definitely a better investment in terms of time.

EDIT: forgot to add that I am talking specifically of high school in Italy, I do not know if other countries already provide more "practical" forms of education to their general population.
