History - you need Latin (and to a decently high level) to do any academic period of history up until around the late 18th/early 19th century. You might not like it, but there it is. Same for most of English, nearly all of theology, Classics of course, ancient history and archaeology, anything that covers historical periods up to the late 18thc (or you simply won’t be able to read a lot of historical material). You’re ok that large parts of our history, literature, etc. become unreadable or unreachable by anyone who wasn’t at a private school?
The thing about Latin is that because it’s a language, obviously you can’t just get to A-level standard quickly later on - you need to build on it from its foundations, whereas people learn accounting or similar from scratch at a later age.
There are plenty of other school subjects that are far less useful. Schools still offer GCSEs and A-levels in sociology, psychology, media studies and so on even though they are taught ab initio at university. Come to think of it, the most absolutely useless school subject is one nearly all student take - English Language, which bears no relationship at all to any university language course and has no real value compared to English literature. Schools don’t even provide proper teaching for it. Yet I don’t see anyone complaining about that (or about sociology or history GCSE or Psychology A-level, for example). Latin actually teaches a core content that is rigorous, undeniably knowledge based, and important as as academic subject - whereas plenty of other school subjects aren’t.
Quite frankly, all the dismissal of Latin is is class envy. Because I don’t see any of those people proposing that we remove everything else from the school curriculum that isn’t “essential” or “relevant” or “important for today”. If we did, we’d junk sport, English literature, history, most of the social sciences, any languages, and anything that isn’t drearily instrumentalist or at all interesting for its own sake, and teach only touch-typing, accounting, coding, and marketing studies. Why not, if everything must be “relatable” and job-oriented?
