Not really. I can read and write in several languages besides English, like Spanish, French and Portuguese. Why should I know a language of savages?(German)

Why should you know German? Well, it is the second most spoken language in Europe, not far behind English and way ahead of number 3 three(French). Also, Germany has been the largest exporter of goods in the world in recent years and is the most translated language. In business, German, Japanese, and Spanish(due to quickly emerging markets in South and Central America) are the most important languages behind English. French not only comes from Latin, but also German; it was created by mixing the two, although I will give you that it may be more weighted toward Latin...the Franks, after all, were a Germanic group. English is also a Germanic language and the Anglo-Saxons were also a Germanic group. Germans(and very Germanic peoples like Austrians and German Swiss) are also responsible for a huge proportion of modern scientific discoveries(For example, in the 19th and the beginning of the 20th century, if you wanted the best education in physics, you went to Germany.) and great scientists(Einstein, Heisenberg, Schroedinger, Pauli, Planck, Euler, etc). They have contributed greatly to western philosophy and literature(Goethe, for example) and many of the great classical composers are German(or very Germanic) such as Mozart, Beethoven, and Bach. Germany has also had a large part in shaping the history of Europe and the world, both good and bad aspects.
