Yes, forget about instructors making a mint. They don't. In fact given their skill, expertise and the time taken to gain the qualifications they are substantially under paid. However it reinforces my earlier point - most private pilots cant and wont pay a reasonable commercial rate, just as most people have to run their hobbies on a shoe string. After all for most it is a hobby. That is why I put forward my argument that the sooner private flying is separated from commercial ops. the better - no compromise on safety - just a different way of going about things. In fact get the majority of private pilots instrument rated and you will improve the record enormously, you will increase the revenue contribution from GA (because more flights will take place) and their will be less "unpleasant" interaction between GA and commercial ops. because pilots will be much less likely to infringe.
Simple really.
Are we getting good at missing the obvious?
