That's the wrong way of looking at it. We have evidence that national cultures affect prosperity, and that, at scale, immigrants bring their cultures with them: https://www.rorotoko.com/11/20230913-jones-garett-on-book-cu... ("For the last twenty years I’ve been asking the Adam Smith question: Why are some nations so much more productive than others? I’d found some new answers in my own research, summed up in my earlier book Hive Mind. But at the same time, I kept reading findings by a separate group of researchers, especially three excellent professors at Brown University: David Weil, Louis Putterman, and Oded Galor. Their work on the 'Deep Roots' of economic prosperity suggested that many of the important economic differences across countries began centuries, even millennia ago.").

The U.S. takes in millions of immigrants a year. At that scale, it's not a question of the individual merits of a single immigrant from a country. It's about the merits of the community that will be formed when 100,000 immigrants from that country come to the U.S. and settle in the same place and socialize their children into their culture. And the evidence we have is that, when that happens, they'll bring with them a lot of characteristics of their origin countries.
