Why do we humans elevate the least evolved among us to positions of the most power?

Why do we humans elevate the least evolved among us to positions of the most power?  The list of "powerful" people, politicians and CEOs, who are psychopaths, whose cravings for power dominate their lives, is extensive.  If you list the politicians and CEOs in power now, how many of them are psychopaths? Most if not all. That means they do not care about anyone or anything but themselves and that which pleases them.  And we see the result. The world is on fire. The social contract has been shredded in the US and is in the process of being shredded in other countries. More violence, more hate, more religious insanity.  Aren't we tired of this?  I know I am.  Aren't you?
