> US attracts talents because there's much more money in US than elsewhere and the political and bureaucratic environment favors entrepreneurship.

I agree. The attitude towards immigrants doesn't seem to affect how well they do anyway. The opportunities matter much more than anything else.

[whimsicalism]

The US has long had permissive immigration policy relative to Europe and that is absolutely one of the largest factors in America's dominance in industry and that immigration policy is a product of attitude towards immigrants. This is true historically - explaining dominance in the 20th century - and in modern tech, capital flows to where it can most effectively leverage high-skilled technical labor and that was the almost exclusively the United States until very recently.
