In the year following the Civil War, businesses began to form monopolies（垄断）. A monopoly is a business or corporation that has exclusive control over a certain market.

Since they had no competitors, monopolies, depending on how essential their product was, could charge as much as they wanted for their product.As more and more monopolies began to appear, some Americans began to wonder how these big companies could so easily drive their competitors out of business. One person who was especially interested in the practices of these monopolies was a journalist named Ida Tarbell.During the early 1900's, Ida Tarbell's articles took on such big corporations as the Standard Oil Trust Company. She described the methods that these monopolies would use to drive rival companies out of business. For example, she described how big companies would make deals with railroad companies. (According to the terms of these deals, the railroad companies would charge the big companies lower rates to transport goods.) Smaller companies who competed with the big companies would be charged the regular rate, which was much higher.
