The story of American history is often told as a hard-won march toward the promise of equality, derived from Thomas Jefferson’s famous proclamation that “all men are created equal.”But this inspiring story obscures a parallel tradition: an enduring and organized argument against equality itself. Again and again, influential Americans have asserted a fundamental inequality among human beings, arguing that the social, economic, and racial hierarchies in which some groups of people rule over others are not only natural but good.In Country of Lords acclaimed historian Kim Phillips-Fein traces this argument for inequality through six vivid archetypes. She discusses the natural aristocrats, such as John Adams, who feared the tumult of too much democracy; the social Darwinists, led by Yale professor William Graham Sumner, who blamed the poor for their own miseries; those who preached a gospel of production, including Henry Ford, who wanted an industrial hierarchy in which the “best” people ruled over compliant inferiors; utilitarian racists who advocated for eugenics and a racial hierarchy; meritocrats like Harvard psychologist Richard Hernstein who described an economic caste system based on “intelligence” in his co-authored book, The Bell Curve; and most recently, technocrats who seem to see themselves as superior because they are closest to the machines destined to outstrip and supplant fallible flesh-and-blood humanity.The anti-egalitarian lineage Phillips-Fein traces is both clear and deeply unsettling. It challenges readers to think about the fragility of the ideal of equality and to reckon with the disturbing arguments of those who have campaigned against it over the past two and a half centuries. Country of Lords is essential reading for anyone trying to make sense of the widening gap between the nation we claim to be and the nation we are becoming.
