Joseph Stiglitz's "The Euro" critically examines the European Union's adoption of a common currency. Stiglitz argues that the euro's design, based on flawed neoliberal economic assumptions, hindered necessary economic adjustments, leading to stagnation and increased inequality within the eurozone. He highlights the failures of austerity measures imposed on crisis-stricken countries like Greece, emphasizing the negative social and economic consequences. The author proposes alternative solutions, including either deeper economic integration or a restructuring of the eurozone into multiple currency blocs. Ultimately, Stiglitz contends that the euro's current structure is unsustainable and detrimental to much of Europe.
