I think you missed the point. The author is not so much advocating the getting of a BA in Liberal arts. He is saying that without the study of "the arts" all one's knowledge in technology, etc is missing out on essential skills and attitudes one learns from the "arts" and that perhaps a well rounded person should have both the "arts" and the "skills". So get your degree in something that gives you a good career..... but don't forget the importance of complimenting that with "the arts".
Many of you missed my point with my original post. I have a liberal arts degree. I also teach high school Latin.
