Differences between andrew carnegie and john d rockefeller

Not sure who the first one is but Rockefeller is a man who had an oil business called Standard oil which eventually became a monopoly or the only option for oil. He ran other small companies out of business so he could buy them out which did without government knowing for several years I hope this helps and fun fact the Rockefeller in New York is named after him

Yeah i’ll call ya tomorrow but i’m not sure if you wanna talk about it later
