Modern economies compete increasingly through human capital. Artificial intelligence, biotechnology, financial services and advanced engineering depend upon unusually skilled individuals whose productivity can be many times the average. An entrepreneur does not merely fill a job. He or she can create hundreds. A scientist may generate intellectual property whose value extends across an economy.
This is why governments that publicly promise immigration control simultaneously construct routes for exceptional talent. The UK-India Free Trade Agreement illustrates the distinction. It does not create unrestricted migration or new routes to permanent settlement. Instead, it guarantees and extends specified forms of temporary business mobility for investors, specialists and professionals while preserving Britain's ability to impose salary thresholds, sponsorship requirements and immigration controls.
Economically, there is no contradiction. A country can rationally want fewer illegal arrivals while wanting more AI researchers. Politically, however, the distinction is much harder. Democratic politics responds not merely to economic aggregates but to perceptions of fairness, identity and control. Voters may accept migration when they believe the state determines who enters, why they enter and on what terms. They become hostile when migration appears uncontrolled or when its local costs appear concentrated while its national benefits seem abstract.
A highly skilled migrant may increase national GDP and tax revenues, while housing pressures, school places or cultural change are experienced locally. Economists can therefore be correct that migration increases prosperity while voters can simultaneously be correct that particular communities bear adjustment costs. The mistake is to dismiss either perspective.
There is nevertheless a danger when democratic competition rewards undifferentiated hostility to migration. Political rhetoric does not remain neatly confined to illegal migration. Internationally mobile entrepreneurs and scientists also hear it. Countries competing for talent are competing partly on salary and taxation, but also on whether talented foreigners believe they will be welcomed. I know, I speak to them daily.
This is particularly important for Britain. The UK-India trade agreement came into force in July and is intended to deepen one of Britain's most important economic relationships. The Government explicitly describes reciprocal business mobility as fundamental to maintaining Britain's global competitiveness. Britain therefore cannot simultaneously tell Indian entrepreneurs, "Build your global company here", while allowing its broader political language to imply, "We would rather you were not here."
The solution is neither open borders nor hostility to immigration. It is selective openness combined with credible control.
A liberal state has both the right and obligation to control its borders. Indeed, control may be the political precondition for openness. When citizens believe borders are governed effectively, governments acquire greater legitimacy to admit those whose skills, investment and enterprise benefit the country. This produces an important paradox. The strongest argument for controlling migration may be that doing so preserves public consent for immigration.
Britain's challenge is therefore not simply to reduce or increase migration. It is to become better at choosing it, explaining it and distributing its benefits.
In the nineteenth century, countries competed for natural resources. In the twenty-first, they compete for human capital. A democracy that cannot distinguish between the entrepreneur arriving to create jobs and the person entering outside its immigration rules risks making a profound strategic error.
It may win the politics of immigration while losing the global competition for talent.
