As someone in academia for 25 years, I agree completely. I believe that adjuncts should be people that have a full-time job (the younger people typically) and/or run their own business (the older people typically) and do it for enjoyment or to give back to academia. Trying to make a living as an adjunct would not be advised in my point of view. I have seen it done and the person had to teach full adjunct loads at three schools to do it. Imagine the schedule and commute!
