How does Rockefeller try to eliminate his competition?

John D. Rockefeller sought to eliminate competition primarily through aggressive business practices such as predatory pricing, where he would temporarily lower prices to drive competitors out of the market. He also employed tactics like forming trusts and consolidating companies to create monopolies, allowing him to control significant portions of the oil industry. Additionally, he used strategic partnerships and rebates with railroads to disadvantage competitors, further solidifying his dominance in the market.
