Englishal,
You're missing the point if you think that unpaid instructors will be providing a service for the benefit of all. Imagine the scenario where you have two instructors working for a school, one paid and one unpaid. Who do you think the school will use when faced by the choice? As profit making organizations, the school would, not unreasonably, use the instructor who presented the lowest overhead ie unpaid. Of course, this amateur, ie unpaid, instructor will have a full-time job, family, life outside aviation so will be unable to provide the commitment to students that the full-time professional instructor would so the students suffer from lack of continuity. Lack of continuity in flying is a euphamism for expensive so amateur instructors (probably) without IR/IMC quals may not save the student much cash. End result is that the only real winners in this game would be the amateur instructors and the school owner; the professional instructors and students will almost certainly lose out. Message ends.....
