The European Union comes in for a lot of criticism, including around these parts. Not all my colleagues have been so critical. Still, burdensome regulations by an unaccountable bureaucracy would trouble any libertarian. But this article in the Washington Post reminded me of the original promise of the Common Market, which grew into the European Union:
The degree to which the European Union’s post‐nationalist vision has transformed the continent is evident in the German region of Saarland, an area of 1 million residents hard on the French border. The region — marked by lush forests, gentle hills and rich coal deposits that once made Saarland an industrial jackpot — has changed hands eight times over the past 250 years. In the past century alone, it was traded between France and Germany four times. The first of those came in the aftermath of World War I, when France claimed the territory as compensation for German destruction of France’s own coal industry. Germany lost the land again after World War II and only got it back in 1957. As recently as the 1990s, the nearby border was subject to strict controls. But today, it’s largely invisible. French citizens commute to Saarland for work or pop by to buy a dishwasher. Germans cross Saar into France for lunch or to pick up a bottle of wine. French — the language of the longtime enemy and occupier — is part of the fabric of Saarland, and it’s welcome. “We’re neighbors. We’re friends. We marry each other. One hundred years ago, we killed each other. It’s been a great evolution,” said Reiner Jung, deputy director at the Saar Historical Museum in the region’s capital, Saarbrücken.
Of course, countries could drop their trade barriers without creating a supranational bureaucracy. But too many people misunderstand economics and believe giving up their trade barriers is a cost, so creating a customs union, a common market, or even a European Union may often be the only way to get the substantial benefits of free trade. And frictionless trade is even harder to achieve without multinational negotiations. So there are pros and cons to arrangements such as the European Union, but we shouldn’t underestimate the great benefits of commerce and movement across national borders.
