It basically made the argument that a college degree isn't an investment but an opportunity. Said that everyone, especially those pushing college as the only method by which to haul yourself up out of poverty, were looking at it the wrong way--instead of being a full-on investment like bonds (which come with a disclaimer that past results don't predict future performance) , it was a chance to increase your own value by adding to your knowledge base.
I think the author, George Leef, is spot on. I've seen students who came in ready and willing to work hard, greedily gathering information and knowledge to themselves--those were the successful students, and the ones I could see succeeding later. I've also seen too many of the other type: the ones that skate through on the minimum, the ones that refuse to try, the ones that expect everything to be handed to them because they sat through their women's cultural studies degree.
Leef ends by saying (and illustrating) it's not the degree, it's the work you put into improving your own value by whatever means suit you best, whether that's a degree in a useful discipline or a set of professional certifications and foreign language fluencies that combine together to make you an attractive proposition to a non-traditional career.
