The most obvious reason to take a marketing class is because business depends to a large extent on marketing. Anyone who is going to make a career out of business can probably benefit from taking such a class. Even if they don't end up in a marketing department, a basic knowledge of the field will be beneficial to them as they deal with the marketing people and simply as they try to think about how to make their firm grow. Some observers of business have argued that it is impossible to separate marketing from business in general. Because marketing is so clearly connected to the overall operations of a business, it makes sense for anyone interested in business to take marketing classes.
