I agree, and wish it was easier for kids to learn languages here - ds is one of the few monolinguals he knows. I did German to A-level but every time I tried to move there so I could move from 'able to deal with almost any situation, read books and papers slowly, watch soaps' to proper fluency, it got scuppered. I did get work to pay for a tutor for a while until they noticed I wasn't making use of it!
It comes in handy for reading rules of board games (most board games are published first in Germany, and the first translations into English are often ropey 'muss nicht' as 'must not' ...), ordering stuff off German eBay sellers, reading the only decent book in the library of a rural Welsh hotel, and of course the odd visit to Germany.
But mostly for making me patient with all the people I meet who don't speak great English, because I really know how hard it is to learn another language, rather than just thinking it can't be difficult if small children can do it.
I'm really annoyed that I have about 100 free TV channels, all but 2 in English (al-Jazeera and I think an Urdu one), and while I could pay £10/month upwards for Sky or cable, the only package that includes any EU languages was £90/month last time I asked! 
Given I don't watch any sport or movies, I've never bothered.
Ds is at least obsessed with the Lingo Show, which is mildly fun but aims so low, 3 words per episode. He can at least say hello, thank you, sausage, cheese and orange in six languages, and is very smug that he knows more Welsh and Urdu than I do. German and a decent vocab with tourist-level French, and basic Italian, Norwegian and Arabic doesn't impress a four-year-old at all...
