I have been totally fascinated by this on the subject of the Wall Street meltdown that brought us to our present unpleasant situation; an elaborate hypothesis on what made it happen is that the "chaotic nature of the modern corporation", with its "rapid change, constant renewal", and ruthless turnover, stopped the boards and other responsible parties from noticing that the companies were being rapidly taken over by charming, charismatic, psychopaths.
Psychopaths who seemed to them not just normal, but "ideal leaders".
This psychopath, the Persian king Xerxes, has a soft spot--he's in love with his tree. I love how the music is heartrendingly beautiful and hilarious at the same time because of the repeated word vegetabile. The YouTubist has thoughtfully provided the aria's one-sentence text so we can follow it.
