I’ve seen examples where hierarchy curbs the positive impact of life giving fellowship. I once observed a leader run themselves in to the ground while the subordinates, myself included, did little more than watch. Why didn’t we say more? We rationalized that it wasn’t our job, it was the job of someone higher up, while the people higher up thought the same. We aren’t in charge after all.
It seems to be terribly difficult for leaders to be real with anyone but their closest inner circle, if that. No accountability mechanism can take in to account our propensity to towards self-deception. The pressure to perform becomes the pressure to be perfect. Doubts, fears, insecurities are pushed back out of conscious thought. Juggling all those thoughts and feelings takes a lot of effort. It is like holding a ball under water. It is very easy for that ball to pop back up.
All that effort saps our ability to process intellectually and emotionally leaving less room for dealing with difficult problems. It seems to me we put leaders in places that make it difficult to be honest and real, which in turn negatively impacts their emotionally health, which severely impairs their ability to lead.
