is college really necessary?

The author gives good points as to why college can be very positive but he also goes into detail with all the negatives attributed to attaining a college degree. I for one do not think college is a necessity; I learn hands on and I can honestly say I have used nothing I have learned in college at my current job. I believe high school should be the limit on education and from there a student should be able to get into an internship for the field they would like to work in. Why should I have to learn about molecules if I want to be a social worker? I hate school because I have to stress over assignments I am not interested in, I have to pay for materials that I will have no use for in a few months, I'm stressing over the cost of schooling when I don't need to even be taking a specific class but I have to or I will not earn my degree. It's crazy. Just as Milennials have changed the American Dream, I think we need to reevaluate our education system.
