Black Swan author Nassim Taleb calls US H-1B visa debate a ‘zero-sum fallacy’

Nassim Nicholas Taleb, author of The Black Swan, has criticised the US administration’s approach to H-1B visas. The philosopher and former options trader argued that skilled foreign workers create jobs rather than take them away from American citizens.

In a post on X on Friday, Taleb said the administration was caught in what he called a ‘zero-sum fallacy’ over H-1B visas. He argued that foreign professionals contribute to the economy by increasing output and spending locally.

“Another way the current administration is trapped in the ZERO-SUM FALLACY: The H-1B visa situation. + You are NOT taking a job from a citizen, rather creating jobs by increasing overall economic output. Plus, these people (even vegetarians) SPEND locally,” he wrote.

Tesla, Von Braun, von Neumann, Fermi & Einstein did NOT each take the job of a citizen. + It the problem is anti-Indian racism, say it, don't play

games.

Taleb also pointed to the United States’ history of benefiting from talent from other countries and that its competitive edge would collapse without it. "The US has long been benefiting from other countries' brain drain; without it its edge wd collapse. Tesla, Von Braun, von Neumann, Fermi & Einstein did NOT each take the job of a citizen," he added.

He also suggested that if opposition to the visa programme was driven by anti-Indian racism, it should be stated openly. His comments come amid a wider debate over skilled immigration and access to jobs in the US.

Microsoft President Brad Smith had also warned that restrictions on green-card access for skilled foreign workers could weaken the country’s technological competitiveness and push talent overseas.

In an interview with Politico, Smith also rejected Vice President JD Vance’s accusations that Microsoft had misused the H-1B visa programme.

Earlier, the US administration suspended PERM labour certification processing for Microsoft, Adobe and six IT services companies with ties to India: Tata Consultancy Services (TCS), Infosys, Wipro, HCLTech, Cognizant and Capgemini.

PERM certification is usually needed when employers sponsor eligible foreign workers for employment-based green cards. The suspension may delay the green-card process for affected employees, but their existing H-1B visas remain valid.

Announcing the suspension,Vice President JD Vance alleged that Microsoft had replaced American workers with foreign employees. "Thanks to an ongoing investigation, we have decided to suspend the PERM program for Microsoft, which means they will no longer be able to take those H-1Bs and apply for permanent resident status within the United States of America,” he said.

Vice President JD Vance announces the suspension of the PERM Program for Microsoft:

"Thanks to an ongoing investigation, we have decided to suspend the PERM program for Microsoft, which means they will no longer be able to take those H-1Bs and apply for permanent resident status within the United States of America. Now our message to Microsoft and to any other foreign or domestic corporation is quite simple. We obviously want you to thrive in the United States of America. We want people to invest in the United States of America, particularly the American technology sector. We’re the biggest boosters of your industry. We want you to continue to grow and to employ a lot of people, but we want you to employ American workers. And so our message to Microsoft is, you’re great American company, but you’ve got to hire great American workers. You cannot lay off American workers and then replace them with foreign indentured servants."
