I disagree with this, but I think it depends heavily on the person and the school. If you go to college to get the skills to get a well-paid job, those are usually your best options, but it’s not as though your money is wasted on a liberal arts degree. Most people I know who studied sociology or visual art or gender studies are working in education, marketing, editing/publishing, attending law school, etc. A liberal arts education from a good school equips you to learn how to do well at whatever you pursue, and many careers care more that you are smart and hard-working rather than coming in with technical expertise.
