The Strange Death of Europe

 I skimmed through this 2017 book  by Douglas Murray. It's interesting, because it's a very Euro-centric view of migration, but you see parallels and contrasts with the concerns in the US embodied in the Trump administration.  Some points which stuck out to me:

• the decline of Christianity 
• the loss of standards by which to judge (adversely) the Muslim immigrants 
• European guilt over colonialism and German guilt over the Holocaust
• governments were always behind the curve in reacting to increased flow of immigrants
• immigrants as violent, crime-ridden, and not integrating into the society
• loss of faith in Europe
• almost total ignoring of US trends and experience
• perspective that societies are unchangeable, that Europeans don't change when they emigrate, that Muslims don't change
• perspective that European culture/society is very vulnerable to change and loss of old historic values
• alienation from modern life, art, 
• the author's perception is that migrants are unskilled, unlike the US where several groups are more highly skilled than the norm for Americans.

One thing which strikes me--human societies have problems with too rapid changes. Sometimes the reaction is over-reaction, throwing the baby out with the bathwater.  Sometimes we can succeed in what I'd call "metering change"--taking measures which tend to slow the pace of change down to a speed which is acceptable.  I think that was the case with the New Deal and subsequent farm programs--they didn't save farmers for good, but they "flattened the curve", spreading the change over a longer time with a slower pace.
