I binged watched a bunch of videos on Europe's various countries' backlash to immigration. An example was a Sweden reversal of attitude on immigration: https://www.youtube.com/watch?v=AmBOqfxPc90
Maybe the statistics in that video was cherry-picked and distorting reality. I haven't been to Sweden in 20 years to know the facts on the ground. Either way, the comments on that video are interesting.
I remember thinking 8 years ago that Trump's rhetoric of "build a wall" was insane. But now seeing the negative attitudes in every country that accepted a mass influx of immigration, it turns out he brilliantly tapped into a frustration that no other high-profile politician running for President was brave enough to say bluntly. It helped him win the election.
