The author is writing about how useless a major to set you up to make money in your career.
That's not what university or college is about- Trade, Techical and professional schools are about that.
I have a degree in Sociocultural Anthropology, which is a social science. I wouldn't trade it for the world. I learned so much about the world and the people in it- but also how to learn, disseminate information, research, critique and elaborate on other's ideas and create my own, time management, and so many other useful skills.
My degree has helped me tremendously in my field, which operations management in the arts/service industry.
You get what you take from the degree.
