In my opinion, every leader expresses exactly the society that elected him. And if we assume that the taste of this entire society is expressed by this leader, then it means this and such a society or a certain community. If you take a group of ten wise people, their leader will be the same person as the totality of all of them, in the same way, 1000 or 100 million intelligent people will not choose one not intelligent. Therefore, the totality of the entire society is an expression of their leaders.
