I'm all for having more useful classes from a very early age--not just relationship/sex ed classes, but classes on 'how to deal with stress' or pre-emptive health/nutrition classes that go beyond your regular gym class. There's more to learn (and not just more, but more universally important) topics beyond RRR (readin', 'ritin', 'rithmetic).
This is an article from the BBC that talks about what they're beginning to implement there. I particularly like the video because nearly a third of it is the teacher chastising Abdul for not paying attention. Ha ha. I want to see the next lesson!
