In 1887, Congress passed an act to regulate the US railroad industry. The legislation originated in the demands of farmers and merchants for protection against the “robber barons”.

Despite this background, railroad interests supported the bill. Charles Adams, president of the Union Pacific Railroad, explained his reasoning to a sympathetic congressman, John D.?Long. “What is desired,” he wrote, “is something having a good sound, but quite harmless, which will impress the popular mind with the idea that a great deal is being done, when, in reality, very little is intended to be done.”

On the whole, he got what he wanted. The Interstate Commerce Commission established by the act was chaired by a lawyer with experience of the railroad industry – acquired, naturally, by acting on behalf of his railroad clients. When, a decade later, the Supreme Court ruled that a rate-fixing agreement between railroads was illegal, the ICC was crestfallen: surely, the commission said, it should not be unlawful to confer, to achieve what the law enjoins – the setting of just and reasonable rates. Soon after, Congress approved legislation making it a criminal offence to offer rebates on tariffs the ICC had approved, and the commission thereafter operated as the manager of a railroad cartel.
