Economic Migration
The Myth of the Migrant Who Only Takes
Every wave of economic migration in recorded history has been met with the same fear — and every time, the data has told a different story.
The Idea
Economic migration is one of the oldest and most misunderstood forces in human history. The standard narrative frames it as a transaction: people leave poor places, move to rich ones, and drain or compete. But the actual mechanics work differently. Migrants don't enter a fixed economy like water filling a container — they expand the container itself. They fill labour gaps, start businesses at higher rates than native-born populations, send remittances that function as direct capital injections into developing economies, and bring the kind of institutional diversity that tends to correlate with long-run innovation. None of this is idealism. It's what the historical record shows, repeatedly. What makes economic migration so persistently misread is a cognitive error economists call the 'lump of labour fallacy' — the intuition that there is a fixed number of jobs, so more workers must mean fewer jobs for everyone else. This intuition feels ironclad. It is also wrong. Economies are not static pools. The arrival of workers creates demand for goods and services, which creates more work. The Roman grain trade, the 19th-century industrialisation of northern England, the post-war reconstruction of Europe — all were powered, in large part, by migrant labour that multiplied rather than divided the economic pie. What we rarely examine is why the feeling of threat is so durable even when the evidence is so consistent.
In the World
In the late 19th century, roughly two million Italians left their country in a single decade — a haemorrhage so dramatic that the Italian government initially tried to legislate against it. Most headed for the Americas, but a significant wave moved to industrial cities across northern Europe and, crucially, to the United States. The reception was hostile in ways that feel startling now: Italian immigrants were classified in some American census documents as a racially distinct and inferior group, accused of depressing wages and importing crime. In 1891, eleven Italian men were lynched in New Orleans — the largest mass lynching in American history — to widespread public approval. Within two generations, Italian-Americans had not only integrated but were disproportionately represented in skilled trades, small business ownership, and the professions. The communities they built — in New York, Chicago, San Francisco — became some of the most economically productive urban neighbourhoods in the country. Meanwhile, the remittances flowing back to southern Italy during the peak migration years represented a larger share of some regional economies than any government programme. The story isn't one of effortless welcome. It is one of contribution persisting despite hostility — which makes it, if anything, a more honest account of how economic migration actually works.
Why It Matters
Understanding economic migration historically changes how you read the present. The arguments made today against migrants — that they suppress wages, take jobs, strain public services — are not new observations. They are very old fears, and they have been tested against evidence across centuries and continents. That doesn't mean every migration policy question has an easy answer, or that disruption and pressure on specific local labour markets never occur. They do. But when you know that almost identical arguments were made about Irish, Italian, Polish, Caribbean, and South Asian migrants in their respective eras — and that those arguments were consistently overturned by subsequent economic history — you develop a different instinct for what you're actually seeing when those arguments resurface. You also start to ask a more interesting question: if the data is so consistent, why does the fear persist so reliably? That question sits at the intersection of economics, psychology, and politics — and answering it honestly tells you more about human nature than almost any other topic in public life.
A Question to Ponder
If the economic evidence on migration has been broadly consistent across centuries, what is the fear of migrants actually about — and what would it take for that fear to update?
