A titanic battle is being waged for Europe’s integrity and soul, with the forces of reason and humanism losing out to growing irrationality, authoritarianism, and malice, promoting inequality and austerity. The whole world has a stake in a victory for rationality, liberty, democracy, and humanism. In January 2015, Yanis Varoufakis, an economics professor teaching in Austin, Texas, was elected to the Greek parliament with more votes than any other member of parliament. He was appointed finance minister and, in the whirlwind five months that followed, everything he had warned about—the perils of the euro’s faulty design, the European Union’s shortsighted austerity policies, financialized crony capitalism, American complicity and rising authoritarianism—was confirmed as the troika” (the European Central Bank, International Monetary Fund, and European Commission) stonewalled his efforts to resolve Greece’s economic crisis. Here, Varoufakis delivers a fresh look at the history of Europe’s crisis and America’s central role in it. He presents the ultimate case against austerity, proposing concrete policies for Europe that are necessary to address its crisis and avert contagion to America, China, and the rest of the world. With passionate, informative, and at times humorous prose, he warns that the implosion of an admittedly crisis–ridden and deeply irrational European monetary union should, and can, be avoided at all cost.
