In contrast to today, Americans in the Gilded Age openly recognized the connection between monopoly power and inequality. They enacted the Sherman Antitrust Act in 1890, and the Clayton Antitrust Act and the Federal Trade Commission Act in 1914, to safeguard themselves from concentrated economic power, which they believed posed a threat akin to political autocracy.
Political power is not the only power to be feared, and sometimes it's a necessary bulwark against corporate power. This is a deeply American idea --Jefferson understood it -- from which we've veered in a radical direction.
Another angle, this one with a surprising local connection: "The decisions culminate a thirty-year trend during which the judiciary, including initially some prominent liberal jurists, has moved to eliminate courts as a means for ordinary Americans to uphold their rights against companies."
