Utter rot, Bose.
This is not about "putting something back in".
As you wish. I think we have to agree to disagree on this. You are clearly driven by a financial need to extract money from aviation. I am not. When I teach I am committed and I think you will struggle to find anyone who has not been satisfied with the quality of my teaching. Many of them on this forum.
Whether I choose to charge or not is my concern and just because more often than not I choose not to believing my reward comes in other ways is my prerogative.
Getting bitter and twisted because you perceive that I might be better off than you just displays a green eyed monster that I would not have expected of you.
