There's nothing fundamentally wrong with hierarchies in a vacuum. The problem is they are often unjustified and unqualified.
A surgical expert leading a hospitals surgery department with the most experienced senior surgeon serving as leaders for less experienced staff is fully justified.
A random billionaire having the ability to dictate the lives of millions of people because they have money is not justified.
