When looking at how wealthy democracies integrate immigrants the English speaking countries are dramatically more successful across all the standard objective metrics like crime rates or income compared to the native population. So Sweden isn't relevant.
Is the UK that particularly better than all the countries on the continent? And comparing US/Australia/NZ with Europe in the regard isn't exactly fair (they are much better at controlling and picking who can or can't come).
US specifically already has extremely high crimes rates (compared to most developed countries) which might overshadow any effect immigrants might have.
The US has very weak employment checks and it's trivial to illegally work ones life here without having to commit any other crimes.
We also have weaker regulations that allow you to start a business with basically $20 and a pressure washer, and you can legalize it with a foreign passport. The English speaking countries generally have lowest barriers to start a business which is a good release valve when you can produce value but racists won't hire you (customers will at low enough price).
I suspect illegals and foreigners in general don't cause so many problems here because its easier to survive helping us than hurting us.
I agree there's near infinite confounding factors. But I think the correlation is striking enough that it's relevant to this conversation especially considering that the post I'm replying to cites only non-Anglosphere countries.
This isn't adjusted by immigrant education/background though?
e.g. in the UK a slightly higher proportion of foreign born residents have tertiary degrees, in France it's the opposite (especially if we look at Île-de-France).
Australia especially is extremely picky (e.g. 60% (immigrants) vs 40%(native))
And I assume there might be other significant cultural/class/etc. differences. e.g. in the US 53% of all Arab-Americans are Christian. I can't quickly find any statistics but I assume in Europe the ratio is very different. Not saying that this specific example necessarily has an impact but differences in other characteristics might.
Generally English speaking countries tend to have and advantage at attracting highly educated/productive immigrants presumably both due to language and other cultural, economic and social factors. It's not at all surprising that their children do a better than average.
