Krugman takes aim at ‘zombie ideas’ – economic myths that refuse to die no matter how often they are disproven. These include claims like tax cuts for the rich boost growth, austerity is always wise, and privatising Social Security is efficient. Through short, clear chapters drawn from his New York Times columns, he explains why these ideas persist and how they distort public debate. He covers topic like healthcare, inequality, trade and financial crises, always pushing for evidenced based policy and exposing bad faith arguments. The book is part economics lesson, part political critique, and part call to arms for using facts to fight misinformation and build a fairer future.
