Hello,

John D. Rockefeller and Andrew Carnegie were crucial platers in the modernization and development of the U.S economy. Although their monopolies devoured their field of business and caused suffering for many under their rule, the lessons we learned on how to limit business has been crucial to the survival of our nation. It is due to the businesses they made and the lesson they taught that we should celebrated them as ambitious “Captains of Industry”

I hope this helps! :)
