Then there would be someone else who'd come. Considering they came to US and not to other places out of Europe. It would mean conditions were favorable in US.
I'm not sure what you're trying to imply, as I can't parse what you mean by "there would be someone else who'd come." Getting the world's 100 greatest plumbers won't fundamentally change the course of the course of the US economy for the better, getting the world's 100 greatest physicists to come to the US certainly puts the US on a path towards world economic domination.
Point is, the 1950s had highly international science, and the US welcomed international scientists and benefited hugely from them.
The US in 2025 and 2026 is extremely hostile to international scientists and is hurting greatly from it.
