I disagree. Although I love working with web technology, I would be miserable if the only things I studied were computer science and business. High school introduces you to a broad range of topics, such as history and literature, that can get you interested in pursuing a liberal arts education alongside your more vocational classes in college. Hell, those liberal arts subjects could even become your vocation. I just believe that it is very important for people to have experience outside of the field they work in.
