It is not a theory. It is an actual conspiracy. From the link: "On April 9, 1947, nine corporations and seven individuals (officers and directors of certain of the corporate defendants) were indicted in the Federal District Court of Southern California on counts of "conspiring to acquire control of a number of transit companies, forming a transportation monopoly" and "conspiring to monopolize sales of buses and supplies to companies owned by National City Lines"[35] which had been made illegal by the 1890 Sherman Antitrust Act. In 1948, the venue was changed from the Federal District Court of Southern California to the Federal District Court in Northern Illinois following an appeal to the United States Supreme Court (in United States v. National City Lines Inc.)[36] which felt that there was evidence of conspiracy to monopolize the supply of buses and supplies.[37] In 1949, Firestone Tire, Standard Oil of California, Phillips Petroleum, GM and Mack Trucks were convicted of conspiring to monopolize the sale of buses and related products to local transit companies controlled by NCL; they were acquitted of conspiring to monopolize the ownership of these companies. The verdicts were upheld on appeal in 1951."
