Ok. I must have failed to formulate my question properly. I'm sorry for that. Let me try again. I know moving is expansive, takes much of time and is really exhausting. But the post talks about scientists. The little interaction I had with scientists have led me to the believe, that it is much more easy for scientists to move even across nations and even across continents. You said moving is no option for americans. Why is that?

Is there a reason for it or is this just internalised american exceptionalism?
