This is one of the most uncomfortable questions in modern politics, yet it exposes the deep illogic at the heart of open-border ideology. We are constantly told that migrants including large numbers of illegal arrivals, are the secret sauce that makes Western nations prosperous, innovative, and dynamic. Diversity is our strength. They do the jobs we won't. They fuel economic growth. Without constant inflows, we're doomed to stagnation.
Fine. Then here's the obvious follow-up: If these people are such world-class nation-builders, why are the countries they're leaving in such a mess? Why don't they make their home countries great first?
The contradiction is glaring. Millions of people from Latin America, Africa, the Middle East, and parts of Asia risk everything to reach Europe, America, Canada, or Australia. Yet the places they flee often suffer from sky-high corruption, weak rule of law, tribalism, violence, dysfunctional institutions, and economic stagnation. If the migrants themselves are the drivers of greatness, their departure should be devastating their origin countries. Instead, those nations frequently remain mired in the same problems generation after generation.
The truth is far more uncomfortable for the migration-maximalists. People are not blank slates. National outcomes are heavily shaped by culture, institutions, average human capital, trust levels, time preferences, and governance traditions. A hardworking, ambitious individual can thrive when transplanted into a high-trust, high-rule-of-law society with strong property rights and markets. The same person, operating within a corrupt, low-trust, clan-based system back home, often cannot transform the broader society. This is selection effect in action: those who migrate are frequently the more motivated, entrepreneurial, or desperate subset of their population. But even they rarely succeed in fundamentally reforming the dysfunctional systems they left behind.
We see this pattern clearly. Countries that export large numbers of migrants — Honduras, Venezuela, Nigeria, Pakistan, Haiti, do not suddenly improve because their most enterprising citizens leave. Often the opposite happens: brain drain accelerates decline. Remittances provide temporary relief for families but rarely build sustainable institutions. Meanwhile, Western countries that absorb these migrants receive an immediate boost from their labour and ambition precisely because they inherit working legal systems, infrastructure, and cultural norms built by previous generations.
Advocates love to credit migrants for "making the West great," but they conveniently ignore that the West became wealthy and attractive long before the current waves of mass migration. Post-war Europe rebuilt itself. America rose to superpower status through its own people, culture, and institutions. Australia and Canada succeeded as settler societies with strong British legal and cultural foundations. The greatness came first, the migration followed the success, not the other way around.
If human capital and cultural attitudes were truly interchangeable, we should see failing countries rapidly transform once a few million of their citizens return home with new ideas. We don't. Instead, attempts at nation-building through migration in reverse (or foreign aid) have a miserable track record. The same patterns of corruption, violence, and institutional failure tend to reassert themselves.
This doesn't mean no migration is ever beneficial. Selective, controlled, legal immigration of high-skilled people who assimilate can strengthen a nation. But the current model of large-scale illegal and low-skilled migration strains welfare systems, social cohesion, housing, and trust, all while the sending countries continue exporting their problems rather than solving them.
The question remains devastatingly simple: If migrants are the key to making countries great, why haven't they made their own countries great? The answer reveals that greatness is not carried in the suitcase of the migrant, it is embedded in the institutions, culture, and human capital of the society itself. Importing people from dysfunctional systems does not automatically import the ability to build successful ones.
Western nations became attractive destinations because they got the fundamentals right first. Pretending that endless inflows will magically fix everything while ignoring those fundamentals is not compassion, it's civilisational negligence. If people truly made countries great regardless of context, the developing world would not need to send its people abroad. The fact that they do tells us everything.
