This naturally leads to a situation where those working at the top are being overwhelmed with demands for their attention and decision making approval.
A conscientious person - arguably a good _leader_ - will take this responsibility seriously, and devote their time and energy to handle all those demands as best they can.
But another type of person - a "player" - will realise that the work of decision making actually _detracts_ from their success within the organisation. A "player" will figure out they should avoid the work of leadership as much as possible and instead devote their time to fostering their own image, gaining popularity, claiming responsibility for other peoples good decisions and generally working their way up the pyramid.
For me hierarchical power structures are the root cause of the problem here, not human nature - the "player" is really acting rationally, taking the path of least resistance to achieve their goals.
The problem IMO is we're using legacy approaches to organising ourselves groups that stems from military theory of the 18th century - that most armies themselves have now moved beyond - see https://www.amazon.com/Corps-Business-Management-Principles-....
We need smarter ways to organise and we probably need AI at some level to help us scale up to higher volumes of effective decision making.
