WASHINGTON, DC – The singular issue of Brexit has consumed the United Kingdom for two and a half years. The “if,” “how,” and “when” of the country’s withdrawal from the European Union, after decades of membership, has understandably dominated news coverage, and sidelined almost every other policy debate. Lost in the mix, for example, has been any serious discussion of how the UK should boost productivity and competitiveness at a time of global economic and financial fluidity.

At the same time, the rest of the world’s interest in Brexit has understandably waned. The UK’s negotiations with the EU have through multiple déjà vu moments, and the consensus is that the economic fallout will be felt far more acutely in Britain than in the EU, let alone in countries elsewhere.

Still, the rest of the world is facing profound challenges of its own. Political and economic systems are undergoing far-reaching structural changes, many of them driven by technology, trade, climate change, high inequality, and mounting political anger. In addressing these issues, policymakers around the world would do well to heed the lessons of the UK’s Brexit experience.

When Britons voted by a margin of 51.9% to 48.1% to leave the EU, the decision came as a shock to experts, pundits, and Conservative and Labour Party leaders alike. They had underappreciated the role of “identity” as a driving force behind the June 2016 referendum. But now, voters’ deeply held ideas about identity, whether real or perceived, can no longer be dismissed. Though today’s disruptive politics are fueled by economic disappointment and frustration, identity is the tip of the spear. It has exposed and deepened political and social divisions that are as uncomfortable as they are intractable.
