Standard Oil was able to use anti-competitive forces against competitors. They specifically were able to extract better rates for the transportation of oil with the railroad companies which helped give them a more competitive cost structure than peers. Because of the high cost of capital required at the time, many peers were driven out of business and were forced to sell to Rockefeller.
I love how ideological nonsense that bears no releationship to historical facts is considered "facts" and by not goose stepping along with your fascist ideology you feel justified in calling me ignorant. When its painfully obvious that all you are able to contribute to the conversation is a poor repetition of your vague memories of the propaganda you were told about the situation, when in reality, vertical integration, including the purchasing of transportation systems gave standard oil a competitive advantage. This is known as competition, and is not "anti-competitive". In fact, if you use the phrase "anti-competitive" seriously, you should lose the right to post on this website because you reveal yourself to be an unthinking socialist, and if you ever managed to start a company, you would surely fuck it up by following your ideology over reality.
