Should teenagers work during high school? Why?

Personally, I think that high school students should work while going to school. For example, when I was a high school student, I had a job at an English bookstore in Budapest, Hungary. I worked every Saturday and Sunday, and sometimes at night during the week. I loved it because I was always meeting foreigners who spoke English. By helping them find books, I was able to practice my English. It was great because at school, I only learned grammar from books, but at the bookstore I was learning conversational English. Not only that but I made money for myself. This helped me because I didn’t always have to ask my parents for money for books and other things. As you can see, by working at the bookstore I killed two birds with one stone.
In conclusion, I believe that all high school students should work part-time during high school.
