That's a very selfless way of looking at things.
Why is learning languages so unreasonable, though? I only started seriously looking at Japanese a few years ago, and already I've come so very far with it. You'd be surprised how far nothing more than a will to learn will carry you in other languages, and how much progress you'll make with no more than an hour or two a day. Though I suppose...you already speak perfect English, so... Maybe you wouldn't be so surprised afterall.
Regardless, if I can learn a foreign language, despite my horrific memory, then I'm convinced that anyone can.
