Nonsense, just because an FI is paid, it doesn't make them a better or worse instructor.
The "best" Instructors I have come across have always been the most experienced. There are very few of us who could get to that level without getting paid.
Compared to the cost of an a/c an FI is very cheap. So why begrudge people a wage? So that some ramshackle old "club" can keep going and perpetuating all the same old myths. Most clubs I have seen are beset with politics and ego's and some are the least welcoming places I have ever found myself. Not all clubs are like this. Mine certainly isn't, but they aren't the be all and end all of GA.
Flying training in this country needs to more professional rather than less and keeping it in the dark ages by restricting investment and earning potential is daft. IMHO.
