We also know that there are plenty of low- to no-cost learning options available to people on a daily basis, from books on nearly every academic topic at the local library and on-the-job experience, to the television programming on the National Geographic, History and Discovery channels. If learning can and does take place everywhere, there has to be a specific reason that people would be willing to spend tens of thousands of dollars and several years of their life to get it from one particular source like a college. There is, of course, and again it’s the credential, because no matter how many years I spend diligently tuned to the History Channel, I’m simply not going to get a job as a high-school history teacher with “television watching” as the core of my resume, even if I both learned and retained far more information than I ever could have in a series of college history classes.
