Rockefeller could literally pay an army of people to fan him with palm leaves, make sorbet from the ol' ice house and make him fresh iced tea as he walked around town if he wanted.

What the fuck does Rockefeller care if the carrying capacity of agricultural land increases due to the Haber process if his personal consumption would remain the five-star best-in-class ingredients for every meal he ever has if he so chooses. He doesn't care about the mean's position. He is the tail.

The existence of air conditioning and the Haber process doesn't make the life of the working poor better than his.
