It's incredibly distressing, but I think the issue here lies with 'we'. Those at the very top are a very, shall we say, unique group. Those who seek power at such a level are not like the rest of us. There's established research showing that psychopathic and sociopathic traits are vastly more common among the "CEO class". It's not that wealth and power _makes_ them so, it's that relatively few are willing to be completely amoral or malicious in order to obtain as much power as possible. I believe that this effect is greatly magnified at the very top.
It's a tale as old as Plato: those most likely to WANT to rule are exactly the 'candidates' who absolutely should not.
Are they unique? What would happen to an ordinary person if you gave them a billion dollars?
One of the things this does is gets you surrounded by supplicants and yes-men trying to tell you what you want to hear to get your money. It destroys social feedback. Nobody will tell you you're wrong. This is not good for mental health.
