* English language school system so your kids (if you have them) will speak a world language.
* Racially and culturally diverse cultures, cuisines, and communities.
* Exposure to goods from most of the world, even if marked up.
* Availability of international franchises headquartered in other countries in major metros.

My partner and I are (different) Asians and the higher-skilled members of our family who wanted to emigrate mostly rejected Europe because of non-English language instruction and honestly just feeling racially uncomfortable in most of Europe. I have some family in Germany (who like it there) so it's obviously not impossible, but European ethnostate thinking is just unattractive to a lot of non-Caucasian talent. Canada, UK, and Australia are not like this and have potentially a lot to gain if the US kneecaps its research bureaucracy.
