That difference is only on paper, purely academical. In reality, almost all the time, this quickly morphs into pushing your kin into positions of power where they make a mess but you still tolerate them because supposedly they are at least somewhat predictable and you don't want to invest the time and effort to build trust with a stranger.

(Or whatever their actual motivation is -- to me it remains mostly a mystery.)
