The Crab bucket is a story for anyone trying to better themselves beyond their current conditions/surroundings and has many iterations, in the UK it's often referred to as the tall poppy syndrome.
The tall poppy syndrome is a pejorative term primarily used in the United Kingdom, Australia, New Zealand, and other Anglosphere nations to describe a social phenomenon in which people of genuine merit are resented, attacked, cut down, or criticised because their talents or achievements elevate them above or distinguish them from their peers. This is similar to begrudgery, the resentment or envy of the success of a peer.
A similar saying occurs in Chinese and Japanese culture that translates to "The nail that stands out gets hammered down".

I think the social phenomena that's most applicable to leaders within a shareholder/company setting is 'You're only as good as your last game/fight/success/movie'.
So you will find after a string of successes a leader can be revered/elevated to god-like status and everyone will follow his path out of the bucket even when it's a bad route/idea and conversely after a string of what shareholders perceive to be poor decisions/results a leader will struggle even when the ideas are good. If a leader finds himself in the latter situation he would need to build a platform again on smaller successes or demonstrate his ability to add value in another way.
