Then when you have committed the 15-20k needed to just get the FI and CPL and you are sat at the club for 12hrs a day and doing no flying don't take the resentment out on your students. That negativity translates into people progressing badly who then give up and the student numbers dwindle further.
Flying Instruction is a profession, it is downgraded by those with more money than sense convincing themselves it is worth it.
My advice is go and piss it out the jet pipe of your JP.
