In "The Privateers," Josh Cowen lays bare the surprising history of tax-funded school choice programs in the United States and warns of the dangers of education privatization. A former evaluator of state and local school voucher programs, Cowen demonstrates how, as such programs have expanded in the United States, so too has the evidence-informed case against them. This thought-provoking work traces the origins of voucher-based education reform to mid-twentieth-century fears over school desegregation. It shows how, in the intervening decades, a cabal of billionaire conservatives supporting a host of special political interests--including economic libertarianism, religious choice, and parental rights--have converged around the issue of education freedom in an ongoing culture war. Through deliberate policymaking, legislation, and litigation, Cowen reveals, an insular advocacy network has enacted a flawed system for education finance driven largely by dogma. Far from realizing the purported goal of educational equity, privatization is failing students and exacerbating income inequality, Cowen finds. He cites multiple research studies that conclude that voucher programs return poorer academic outcomes, including lower test scores on state exams, especially among students who are at greater academic risk because of their race, their religion, their gender identity, or their family's income. Continued advancement of these policies, Cowen argues, is an assault on public education as a defining American institution.
