Generally, I would agree with you SD that problems can exist on each side. Those certainly can be and are magnified in our area where there is so much wealth which can be translated, unfortunately, to power.
From experience, I don't think it is awfully hard to identify "bad coaches" or even good coaches who are doing a "bad job." Those two can be very different.
Where I have likely differences with you is my perspective that too many parents are not able to recognize good coaches, doing a good job, who are successful in teaching and coaching the game (and life lessons within it). Far too often, those are the coaches being driven out of coaching and far too often it is for the wrong reasons.
