I believe Latin is still offered in my high school system... A guaranteed waste of time.
I truly believe study of foreign language should almost be reserved for people who will be living in a country with that tongue. Using it everyday and getting good returns on all that grind.
More generally, we should be be more economical with our effort and time. "Why am I learning this? " Should be asked more often.
I feel the cultural pull for pointless learning on other subjects. I am sure we all do. "I should study some physics. Read Feynman's lectures." But to what end, I don't know. My life will not be appreciably better for learning more about electro-magnetism.
There's a yearning in us that pointless education must satisfy. A dream of a better life that you can pretend to be working towards.
