I watch birds fly around, and they seem to need no wealthy heir birds, inheriting the right to expropriate the value of surplus worker time of the birds searching for seeds to eat. "We", the poor humans, apparently need the wealthy to have jobs. The inhabitants of Sentilinese Island and the hunter gatherers still roaming around the Amazon seem to make do without these wealthy people bestowing the gift of jobs upon them. I suppose Russians had the beneficence of the czar and his family to thank for their living as well - that is until the Bolsheviks blasted and then bayoneted them all. Somehow, jobs seemed to continue in Russia after they were gone.

Take Japan Airlines CEO. Certainly well paid but does not earn the crazy amounts that western CEOs of large companies tend to earn.

You can have everything you stated as a benefit without the requirement of a person who runs the company having to be wealthy.
