Totally agree with what das Uber Soldat has stated above - very well put!
There is definitely a place for junior pilots as Flight Instructors - but they must have a desire to teach & provide a service to those they teach. I find that experienced pilots (as Instructors) can bring good context to training for the "real world", whilst the experienced Instructors can fix the problems students have - quickly & with insight (ie remediate efficiently). The young / junior Instructors, despite their possible lack of practical context & flying experience, bring the enthusiasm that kindles the fire of the aviation dream - they represent the "achievable goal" that prospective CPL trainee wannabes can connect with at the early stages of their training.
Remember, the Instructor Rating is the one rating a pilot holds that will mess with other people's careers. What the Instructor does not teach that he should, or teaches that he should not - will potentially adversely impact on someone else's flying, either as a lost opportunity when they are not successful chasing that first job, or worse - should they ever find themselves in a situation for which they have not been adequately equipped...
So, if you have an altruistic streak & actually enjoy working with others - go for it, become an Instructor & welcome to the team (maybe drop in & speak to me - I'm always looking for the right people!). God knows that the industry needs dedicated Instructors & as already stated - the pay ain't great (I think that has less to do with individual flight school owners & more to do with the commercial realities of the "race to the bottom" caused by sausage factories - a discussion for another day!). However, if you're simply seeing it as a mechanism to watch the VDO roll over & put numbers in your logbook at someone else's expense - please don't get involved. Go to the NT like all the other lads / ladettes & chase the charter role.
