Illiberal Reformers: Race, Eugenics, and American Economics in the Progressive Era is a book written by Thomas C. Leonard and published by the Princeton University press which reevaluates several leading figures of the progressive era of American economics, and points out that many of the "progressives" of the late 19th and early 20th century who created policies such as minimum wage and maximum-hours laws, workmen’s compensation, progressive income taxes and many others had beliefs rooted in Darwinism, racial science, and eugenics, revealing a dark underside to the economic reformers often considered by history to be the altruists in the story of American economic progression.
