I see that you deleted your further attempt to mock my presenting statistics in exchange for your anecdotes (I had no idea until reading your contributions here that that in the US there is no "actually having friends, nature, having hill-climbing organizations that aren't only lobist groups to be actually allowed to climb the mountains").

But since you did bring up Germany with the deleted mention of Operation Paperclip, I suggest you read https://news.ycombinator.com/item?id=25367731 , in which @bildung and I discuss German migration to the US over the past 30 years (including 2019 data).
