Rockefeller built an enterprise that continues on to this day. An empire that has seen nineteen American presidents come and go, watched superpowers rise and fall and is (IMO) the most important company in history.

Exxon still breathes Rockefeller, his imprint can be seen all over that company. To call him a visionary is absolutely appropriate.

I don't oppose all improvements in human quality of life that have a potential negative environmental impact.
