Given the nature of the training industry in aviation one can not rise to that level within the structure that we have in the flight training industry, and even if one could somehow teach in a manner that does not fit the structure of the flight school you would have to be like mother Theresa and devote your life to poverty.
I instruct. In a CLUB. not a school. It doesn't cost me, I am paid expenses. Normal procedure in France, part time instructors doing it to pay back the instruction they had from volunteer instructors. No vow of poverty needed.
