What about UK, how did that work out for them? I can't see the charts.
I agree it's not enough evidence for anything conclusive. But I think it's enough evidence to say arguing about what will happen to the US based only on Sweden data is unsound.
Ask immigrants or the children of immigrants (like me).
Western Europe are just extremely insular and passive aggressive and will gladly bury their head in the sand regarding their own racism.
Anglo countries at least tried to tackle racism by introducing education about racism (eg. Civil Rights Movement in US, Aboriginal Rights Movement in Australia, First Nation's Movement and racial quotas in Canada, the anti-Skinhead movement and the trade union lead anti-racism movement in the UK) and trying to build an identity that trascends race or ethnicity.
Similar movements happened in mainland Europe as well, but aren't taught about, so mainland Europeans remain insular in their mindset.
To me this has a simple answer: (Western) countries with English as the primary language are all New World countries, with the obvious exception of the British Isles nations.
This is especially true for second-generation immigrants. First generation immigrants are general less likely to commit crimes, but in countries like Germany and France the rate rises significantly with the second generation. That doesn't happen in the US or Canada, for example.
The children of immigrants in English speaking countries tend to do better financially than their parents whereas in many non-english speaking European countries the children of immigrants slide into poverty.
