A century ago, in one of his last acts of office, President William Howard Taft attempted to solve the problem of inequality in America. In August 1912, on the cusp of a brutal third-place finish in the presidential election, he created a Commission on Industrial Relations to investigate “the general condition of labor in the principal industries.” Despite its fusty charge, the commission turned out to be one of the most sensational sideshows of the Progressive Era, a cross-country journey through the wilds of American class conflict. For three years, government commissioners traipsed from city to city asking capitalists, union organizers, and reformers what it was like to work in America, and whether the spoils of industry seemed to be distributed fairly among the rich and poor.
