Why would a course in marketing be helpful even if you don't pursue marketing as a career?

I personally am a sociology major/management minor and I am taking marketing because it is required knowledge for those possibly pursuing some type of business career. However, a marketing course could be helpful to a student in any major because marketing is a huge part of everyday life. So much of a person's daily routine has marketing in it whether or not they directly notice it. For that reason and many others, taking a marketing class could help a person learn more about products and services and how they are advertised to society. Also, it is important to understand the difference between accurate and false marketing so as a consumer you can make well-educated decisions. Even if your future career doesn't seem as if it will require marketing or marketing skills I guarantee having a basic understanding of how things are marketed and why will be useful to have under your belt.
