...And the euro, he argues, was built — and run — on illusions, the illusion that Germany was Italy, Italy was Portugal, and Portugal was Finland, the illusion that one size would fit all. Its creation was a “reckless gamble.” Politics prevailed over economics. No one made any preparations for the rainy day that could never come. The foundations for catastrophe were laid, and then built on by regulators, policymakers, and financial-market players only too happy to believe that the impossible was possible. Imbalance was piled on imbalance, and a shared currency masked the nightmare developing underneath. Employed by Goldman Sachs at the time, Nordvig saw how markets viewed the euro zone as an indivisible whole. But Greece was still Greece. And Germany was still Germany.
“Policy makers,” writes Nordvig, “can attempt to circumvent the basic laws of economics, but over time, the core economic truths take their revenge.” Unsustainable boom was followed by what has seemed, until recently, like permanent bust.
