Inside a monetary union, Germany gained competitiveness by holding nominal wage growth below productivity growth, not by out-innovating its partners. Periphery members could no longer devalue their currencies, so their unit labour costs rose relative to Germany's. The result was chronic German current-account surpluses that were mirrored by periphery deficits.
Treat a monetary union as a hierarchy, not a club of equal fiscal actors. Surplus core states export capital and goods, and deficit periphery states absorb them. Seen this way, periphery debt is the balance-sheet counterpart of core surpluses, not evidence of national moral failing. Blaming individual governments' spending hides the systemic flow that produced the debt.
A single currency takes exchange-rate and national monetary-policy adjustment away from a member state, which leaves internal devaluation as the main route to regaining competitiveness under the union's rules. Internal devaluation means cutting wages, prices, and public spending. The book argues this puts the burden of adjustment largely on workers in deficit countries and deepens recession by depressing demand.
Core-country banks recycled their surpluses as cheap credit to periphery households, firms, and states. When the 2008 financial crisis hit, private banking exposure became a sovereign problem through bailouts and ECB-backed rescues. Bailout programmes mainly protected core creditors rather than periphery economies.
The dominant story says Greek and other periphery governments caused the crisis by overspending. That story does not explain why Spain and Ireland, which had low public debt before 2008, also collapsed. Their crises came from private credit booms and lost competitiveness, not public deficits, so austerity treats the wrong disease.
The book sets out three paths for the periphery: prolonged austerity inside the euro, an unlikely federal reform with fiscal transfers, or default and exit from the monetary union. It argues that a default led by the debtor rather than by creditors, followed by exit and devaluation, would restore policy sovereignty. It says this would require capital controls, bank nationalization, and shifting the costs of transition toward capital.
