You are right. The aging tech is a problem. Where you are locally there may be a low demand for apprentices or new techs, but here I have a hard time even getting applicants. Research the archives for http://www.aveoforum.com/forum/f81/help-wanted-16673/. I was so desperate for a tech I even posted a job on here. - no takers. Our shop runs with 2 - 3 techs and an apprentice. My lead tech is 50, my second tech is 38, and my apprentice is 28. In the past the boss has taken on apprentices as young as 17.
