What is the best career path for me? Something where I make a lot of money, and help people around the globe?

I just recently graduated High School and I'm thinking about what I should get my B.A in. I am a very International person, I'm Persian/Iranien who was born and raised in Germany. I speak 5 languages Farsi, German, English, French and Spanish, but my overall goal is to be Fluent in 7 languages! (possibly Arabic and Russian) ... i know sounds crazy but I can be a pretty valuable person :D. I moved to L.A. when I was 13 and finished Middle School and High School here. I'm a very friendly, honest , blunt, and caring person and therefore wanted to be some sort of an International Advocate, who helps a lot of people in desperate need around the globe (help fight against child prostitution in India; Help fight for Women Rights in countries like Iran and other middle eastern countries; perhaps work for the United Nations to push them to ensure peace around the world; etc.) After that I heard that the United Nations doesnt do anything and that the pay is low . I could become an Interpreter for private companies... but that doesnt help people around the world. I think it's very unfair that us Americans get to live this Luxurious Lifestyle while other countries are in desperate Help... but we do donate a lot of money though. So yah, if anyone has an idea, then feel free to answer :)
