I really hate that line of thought. If it wasn't for academics we wouldn't have many of the advances we have had. Many academics also work in the so-called real world. Don't perpetuate the crap that if you can't do it, you teach it. I have had the pleasure of working with academics on real-world projects and they bring an understanding that practitioners often do not have.
BTW he is not a professor, he is an associate professor. He needs one more promotion to be called Prof.
Having said that, there are also plenty of academics who do not have a clue and IMHO these are the one's most likely to be experts on TV. This guys bio at UWS includes "... pre-academic career included periods of journalism, in fields as diverse as economics commentator for the ABC's Indian-Pacific program and software editor for Australian Computing." Therefore I am a bit sceptical.
I'm not saying he is wrong but he does have vested interests. He sells books. His promotion to Professor will be influenced in part by his national reputation and how many other publications refer to his work (under the Research Quality Framework funding model). Plus he may want to get more involved in public speaking and conferences. So a bit of publicity helps.
What I don't understand is: if I keep my job and can afford to service my debt now, and if interest rates do not go up, then why is this debt suddenly a problem?
