Hey there!
English classes are an essential part of education, as they enhance your communication, and social skills. The techniques and skills that you learn in English class, can make for better and more powerful writing, fluent reading, and correct grammar when speaking, and learning these skills can make you a better, and more persuasive person. English classes also (at least in my experience) teach you how to get ideas across to others. You can have an idea, but without the proper way to address it, it just remains a thought, and not a plan in action. Thus, this is why I believe that english classes are essential to education.
Let me know if this helps :)
