Although VFE put his point across in the wrong way i think that he may have a point. We have seen latley that instructors wages are starting to rise to an almost live-able rate and this is because that there is a shortage. In turn many people that i know are now willing to become flight instructors, as with the pay increase they are now able to eat and some can even afford bread to go with their beans. If PPLs start to become instructors, not only will the pay begin to fall again because others are willing to do the same job for free but the same people who were previously willing to become instructors wont because they simply can not afford to.
Having said that, I know many very experienced PPLs that would make fantastic instructors and I have learned a lot from flying with them. I just wish that they would be allowed to charge for the services.
