Learning a Language, is there a point???

Did you ever think learning a language is hard. Well we all know we have to take a language in Middle School, but for what??? Is there a point in taking a language??? I mean, sure you can communicate with other people who don't know how to speak English, but they speak another language,and you know that language. But here in Indonesia you don't need to speak Spanish, Mandarin or French. The only language you need to learn is INDONESIAN!!!  It's a good thing I speak Indonesian fluently, so I don't have to learn it in Middle School, because that just means  EXTRA HOMEWORK!!!  Now I am currently to learn spanish, which I hate more and more!! :-{
