Thank you for your comment.

I found this book worthy presentation because it offers solid data in opposition to speculations of what could happen, as you do.

Swedes took an ideological approach, and it has its price. Pragmatic Germans took proportionally to population a comparable number of refugees, and they are doing much better, https://www.cgdev.org/blog/five-years-later-one-million-refugees-are-thriving-germany

Your comment goes into discussing our immigration policy. I could elaborate extensively on this subject, but I do not need to because I already have done it. I have been writing on the subject for the last 15 years. Among 82 of my articles on Medium, 17 (20%) are about immigration. I suggest that we abandon our immigration policy and adopt the freedom of migration concept. I have a website dedicated to this idea: https://www.freedomofmigration.com/about/.

Please check my response to Good mannered as well.
