In recent years, most of the debate around the global migration of people has focused on the movement into developed countries and the political battles that ensue. Most famously, Trump has overturned the wisdom of the American political establishment by saying the unsayable on immigration. Politicians from Riga to Rome have won votes (and office) by exploiting similar anxieties. But we seldom talk about the places which, year after year, see more people leave than arrive, and the consequences of countries saying goodbye to some of their best and brightest—often for good.
Nowhere is this concern more pressing than in Eastern Europe. According to the UN, of all the countries that are expected to shrink the most in the coming decades, the top 10 are all in the eastern half of the continent, and seven of those are in the European Union. One cause for concern among many of these countries is the EU’s freedom of movement, one of the four “fundamental freedoms” of goods, capital, services, and people that bind the 28. Although most press coverage of the bloc’s easternmost nations has focused on the rise of anti-immigration populism, there is mounting concern about the brain drain of its most highly qualified citizens to better jobs abroad. In at least six of the EU, the people leaving have become as controversial as those arriving, with some countries now favouring emigration controls.
In essence, the EU’s freedom of movement guarantees an absence of barriers for anyone looking for a job within the 28 countries and makes discrimination based on nationality in work or employment illegal. For many of the EU’s new entrants in the East—including Poland, Hungary and Romania—a future where capital and people could move more freely between themselves and France, the UK, or Germany looked like a fast-track to the top-tier of developed nations. But somewhat ironically, it has only accelerated the departure of those who are crucial to getting there.
