Step-by-step explanation:
Andrew Carnegie wanted to take the title of the richest man in the world from John D. Rockefeller. Both Carnegie and Rockefeller were incredibly wealthy businessmen during the late 19th and early 20th centuries. While Carnegie made his money in the steel industry, Rockefeller was the founder of Standard Oil, a massive oil conglomerate.
To compete with Rockefeller, Carnegie sought to control every aspect of steel production and lower costs, which included direct ownership of mines, foundries, and railroads. He wanted to surpass Rockefeller's wealth and solidify his position as the wealthiest individual in the world. Overall, Carnegie and Rockefeller were both titans of industry who competed for wealth and power during the Gilded Age.
