Needs to be changed, not explained
Speculating over why it’s happening may keep the analysts and commentators busy, but it’s tiresome and irrelevant. If the bad behaviour can be stopped by removing the cause, then let’s do that, but if we cannot determine the cause, then let’s accept the fact that it will continue unless we change it.
The best way to help change the behaviour is to allow the negative consequences to be evident and obvious to the individual and to his supporters, facilitators and enablers. It doesn’t matter if it’s an arrogant politician or selfish CEO, delinquent employee or spoiled 5-year old. Let's change the behaviour or change the player.
(OK, maybe not change your 5-year old, he'll grow up and improve.)
Be better. Do better.
Your Uncle Ralph, Del Chatterson
