What happens when you need immigrants, but don鈥檛 want them?

The topography could hardly be more different: nearly 2,000 miles of cityscape and desert separate the United States from Mexico, while Britain鈥檚 southern coast, famed for its White Cliffs of Dover, is washed by the chilly, choppy waters of the English Channel.

Yet both the U.S. and Britain are at the eye of similar political storms: about how to establish control over a surge in migrants ready to risk imprisonment, deportation, violence, even their lives, to escape the lands of their birth.

That control could prove doable, if difficult. But the scramble for short-term policy fixes is masking a pair of deeper, long-term challenges facing the U.S., Britain, and other European nations.

Two challenges, with a clear policy message: Border control is only part of the answer.

Challenge number one is that the 鈥渕igrant issue鈥� is not a short-term problem. At the turn of the millennium, some 175 million people worldwide were living outside their native countries. That figure is now nearing 300 million. It is a tide swollen by wars, persecution, autocrats鈥� brutality, dysfunctional or collapsed states, the intensifying effects of climate change 鈥� and, quite simply, a lack of basic economic opportunities across much of the world.

Challenge number two is that the developed countries are aging. Their economies need workers in a range of services and industries 鈥� a need that is also feeding inflation and pushing up interest rates. And a 21st-century economy, in which innovation is critical, also benefits from immigrant researchers and entrepreneurs with a track record of contributing disproportionately to their new countries鈥� achievements.

Tackling those twin challenges, too, could prove doable, if difficult.

The problem isn鈥檛 policy. There is a broad center-ground consensus on what鈥檚 needed: immigration policies that welcome newcomers with the skills beneficial, and necessary, for their new host nations; a policy toward migrants that combines strong border security with an effective system for considering their cases; and initiatives to improve conditions in the countries they are fleeing.

What is holding back such an approach is politics: An increasingly partisan, populist, nationalist tone now colors the immigration debate in the U.S., Britain, and other Western democracies.

It is manifested in some politicians鈥� talk of a migrant 鈥渋nvasion,鈥� a term British Home Secretary Suella Braverman used last year. And while many people are indeed worried by the changing ethnic mix of their communities, these concerns are sharpened by conspiracy theories such as the so-called Great Replacement, the notion of a shadowy international scheme to replace white, 海角大神 natives with interlopers of different colors and faiths.

The result? A hardening of attitudes not just toward migrants arriving by rubber dinghy on the south coast of England, or crossing the Sonoran Desert on foot, but toward immigrants more generally.

In Britain last week, Ms. Braverman, who is Prime Minister Rishi Sunak鈥檚 chief law-and-order minister, pressed him not just to make good on his vow to 鈥渟top the boats鈥� carrying desperate migrants to British shores, but to cut back sharply on all immigration.

Net migration into the U.K. reached a record high of around half a million last year, and it鈥檚 still rising. Ms. Braverman wants at least to bring it in line with her Conservative Party鈥檚 election pledge of four years ago, around 270,000 a year.

That presents a daunting problem for Mr. Sunak. A key selling point for Brexit, when Britons voted to leave the European Union, was that London would be able to keep out the East European plumbers, construction workers, and seasonal fruit and vegetable pickers who, as EU citizens, had enjoyed the right to work in Britain.

The new, non-EU influx 鈥� mostly from India, the Philippines, Nigeria, and Zimbabwe 鈥� has simply reflected market realities. These jobs still need doing, and Britons either can鈥檛 or won鈥檛 do them.

In America, too, the partisan debate over the southern border has undercut prospects for consensus on wider immigration issues.

Former President Donald Trump rode tough talk on border security to victory in 2016. His closest Republican Party challenger for the 2024 nomination, Florida Gov. Ron Desantis, is staking out an equally hard line. Speaking last weekend, Mr. DeSantis said he would 鈥渟hut the border down immediately.鈥�

Still, real-life pressures are likely 鈥� eventually 鈥� to prod politicians toward a policy mixing a better-funded, better-organized system to control migration, with an economically targeted welcome for immigrant workers.

In Britain, Chancellor of the Exchequer Jeremy Hunt has been pushing back against Ms. Braverman鈥檚 call for a wholesale reduction of immigration, arguing that this would damage economic growth. In fact, he said this week, he was open to expanding the list of 鈥渟hortage occupations鈥� 鈥� jobs where business is pressing for greater numbers of immigrant workers.

But in the U.S., the increasingly charged partisan divide seems likely to frustrate any bipartisan immigration breakthrough, at least for now. That last happened in 1986, under then-President Ronald Reagan: a crackdown on illegal immigration paired with an amnesty for tens of thousands of immigrants already in America.

In his as president, Mr. Reagan chose immigration as his theme. Calling it the 鈥済reat life force of each generation of new Americans,鈥� he said America鈥檚 strength rested on drawing in people 鈥渇rom every country and every corner of the world.鈥�

鈥淚f we ever closed the door to new Americans,鈥� he warned, 鈥渙ur leadership in the world would soon be lost.鈥�

Mr. Reagan鈥檚 legislative success provides a possible template 鈥� but also a reminder of how dramatically U.S. politics, and his own Republican Party, have changed over the past 40 years.
