If one were to trace a single thread running through the most disruptive political shifts of the Euro-Atlantic world in recent decades—from Donald Trump’s rise in America to Brexit in Britain and the populist tremors reshaping continental Europe—it would lead, unavoidably, to the question of mass immigration.
From the vast and scorched borderlands of the U.S.–Mexico frontier to the restless waters of the Mediterranean, population pressures from the global South have redrawn the political map of the West. At first glance, the challenges appear similar. But a closer look reveals a tale of two models—divergent in structure, outcomes, and the political outcomes they have set in motion.
At their core, both the United States and Western Europe share a structural predicament: they are wealthy, politically stable societies, but bordered to the south by youthful populations from poorer, less stable regions. For America, it is Latin America; for Europe, the Middle East and sub-Saharan Africa.
This has made both regions enticing to those eager to emigrate. Combined with low native fertility rates, the result has been a profound demographic shift. In both cases, populations of European descent have shrunk—fueling cultural unease while energising anti-immigration movements. In the US, the share of non-Hispanic whites fell from over 80% in 1970 to under 60% today. In Germany, the UK, and Sweden, the share of residents without a migration background dropped from over 90% to around 70%—a transformation which occurred within a single generation.
Not All Borders Are Equal
Yet they diverge in significant ways. Latin America, with around 650 million people, is roughly twice the size of the US and is now seeing a steep decline in fertility. Countries like Mexico, Brazil, and Colombia already have lower birth rates than the United States. In short, these countries’ demographic surplus is shrinking. Europe, by contrast, faces a far more daunting prospect. The Middle East and Africa together hold close to 2 billion people and continue to grow at a rapid pace—dwarfing the 500 million citizens of the EU and UK. Compounding this is Europe’s deeper demographic malaise: native fertility has long been lower than the US’, accelerating the pace of ethnic change, even if it remains less immediately visible.
Immigration to the US has also become more diversified. Asian migrants—especially from India, China, the Philippines, and South Korea—now account for 35–40% of new green-card holders, matching or slightly exceeding Latin America’s share.
This introduces a critical distinction: selectivity. A striking example can be found in the divergent experiences of Pakistani immigrants to the US and the UK. In America, Pakistani-Americans are among the most economically successful groups, with a median household income of $105,000—higher than white Americans—and a 54% college education attainment rate.
In Britain, Pakistani-origin households have a median net worth of £232,200, well below the white British average of £324,100. The combined Pakistani and Bangladeshi population has the lowest employment rate among major ethnic groups, at just 61%. The reason is not discrimination. American immigration policies tend to let in those from Pakistan’s urban, educated classes; in contrast, Britain’s Pakistani community largely stems from rural areas like Mirpur in Azad Kashmir.
Borders and Belonging
Geography plays a powerful role here. North America’s insularity makes spontaneous, overland migration from the Old World impossible. One cannot simply walk into America. This alone filters for more educated and formally vetted migrants. The result is a growing economic divergence. While the net fiscal impact of non-EU migrants is negative in most European countries, studies consistently show a neutral or positive contribution in the US. Welfare dependency among migrants is also markedly higher in Europe. The manner in which institutions are designed matters greatly: America’s relatively lean welfare system creates stronger incentives to work. In contrast, Europe’s more generous social safety nets can enable long-term dependency, particularly among lower-skilled migrants with limited language skills.
Then comes the cultural dimension—arguably the most volatile. Most of Europe’s new arrivals come from Muslim-majority states. Their social norms often differ greatly from secular, historically Christian host cultures. Yet culture and economics are deeply intertwined. A skilled Pakistani engineer relocating to Silicon Valley is far less likely to trigger friction than a low-skilled migrant settling in a struggling suburb of Paris or Birmingham.
American identity, meanwhile, is inherently more flexible. English is the global lingua franca, and the very concept of American-ness has been shaped by successive waves of immigration. In contrast, Europe’s national identities—formed through centuries of defining the in-group—render integration more difficult. The result is a continent more prone to cultural neurosis in the face of large-scale demographic change. In contrast to America’s model of selective assimilation, Europe’s mix of demographic pressure, the institutional subsidising of new arrivals, and tribal national identities leaves it more vulnerable—politically, economically, and socially. With each passing year, the costs of these differing approaches will become ever more apparent.
Statement
Mass immigration has reshaped the political and demographic landscape of both the United States and Europe, yet in markedly different ways. While both regions face population pressures from the global South, the US benefits from geographic insulation, selective immigration based on economic benefit, and a national identity rooted in assimilation. Europe, by contrast, confronts a far broader frontier through which migrants can pass, lower native fertility, and welfare systems that often discourage integration. Cultural tensions are more pronounced, particularly with immigrating Muslims. As America absorbs its newcomers, Europe’s model—less selective—risks deeper political instability.
