Immigration was how humans discovered the world. Now it's a controlled substance.

We walked out of Africa and just kept going. We built rafts, then boats, then ships, crossing oceans based on rumours of land. Movement is not a feature of human history; it is the engine of it. It was how we discovered there was a world at all.

Somewhere along the way, we decided this instinct was dangerous. The nation-state is a recent invention, historically speaking, but we guard its imaginary lines with a religious fervour. We have convinced ourselves that a person’s birthplace should be the primary determinant of their destiny. An accident of geography now dictates whether you have the right to move, or the obligation to stay put.

Let’s be clear what borders are for. They do not protect culture; that is porous and ever-changing. They do not truly protect security; capital, ideas, and threats move digitally at the speed of light. The primary purpose of the modern border is to ration prosperity. It is a valve, designed to maintain a global imbalance of opportunity. A border is not a shield; it is a dam, holding back human potential to protect an artificial reservoir of wealth.

The British government’s scheme to fly asylum seekers to Rwanda is the logical conclusion of this worldview. It is policy as performance art. It treats human beings not as people with agency, but as a logistical problem, a negative entry on a national ledger to be offshored. The goal is not to solve a crisis, but to demonstrate a theatrical cruelty that might deter others. We are not deporting people; we are exporting our own humanity.

Consider the term ‘brain drain’. The phrase itself is telling, framing skilled workers as a natural resource leaking from a developing country. But this is not a passive leak; it is an active siphoning. Our immigration systems are designed for extraction. We welcome the surgeon, the engineer, the programmer, but we give them a one-way ticket. The system makes it exceptionally difficult for that person to circulate, to work in London for a year and then return to Lagos or Manila to build a business or transfer skills. We take the talent, and our rigid visa regimes prevent the source country from ever benefiting from its return.

This is the one-way ticket problem. Human migration has always been a story of circulation, of networks, of back-and-forth. People would leave, earn money, gain experience, and often return. Our current system abhors this fluidity. It demands a binary choice: you are either in or you are out. It creates permanent exiles instead of dynamic diasporas, severing connections that would otherwise enrich both societies.

The cost of this is immense. It stifles innovation, creates grotesque inequalities, and wastes human potential on an industrial scale. We are so obsessed with guarding what we have that we prevent the creation of so much more. Prosperity is not a finite commodity to be hoarded. It is a positive-sum game, and for all of history, movement has been how we win it.

We have mistaken the lines on our maps for the boundaries of our humanity.
