With his Amazon warehouses, for most of his employees he's created the terrible future of poverty and misery that he allegedly dreams of saving humanity from with his space colonies. And his success isn't built on any innovation other than relentlessly keeping as much as he can for himself.
I have been working for Amazon for over 2 years and I dont live in poverty or misery. In fact, thanks to my pay at Amazon (2x the minimum wage in my area) I can live quite comfortably. Thanks to my job I dont stress out when I think about my student loans. And thanks to the innovation which was implemented with robots, my job is a lot easier that what it would be without the assistance of the electronics we use.
You have to be fantastically greedy to work so hard and for so much time to get an unfathomable quantity of money and keep going. I suppose there is nothing intrinsically wrong, but there is no need of Freud to tell us that greed is a very strong motivation to him.
