But evidence shows that they do emigrate in mass when there's a reason, it's one of the core issues of the last decade and the reason why fascists gained power all over the world. If fact its the reason why masked people in USA are hunting down immigrants.

Its also factual that there's a large scale migration intra-EU, with people from poorer countries moving to rich ones to seek jobs. Bulgaria, Romania and Poland are prime examples for that.

Its also well documented that those same people stop migrating and even coming back once their counties level up with the rest of the EU, again Poland and Bulgaria are good examples for this in the last years.

EU is trying to make sure that the poorer countries receive the help they need to catch up and it looks like its working.

If you go to the CNN website there are lots of articles on there right now (e.g. https://edition.cnn.com/travel/us-woman-moved-to-germany) about US peeps who have emigrated to Europe recently and are thoroughly enjoying their new life with no plans to return to the motherland in the foreseeable future.

I can't possibly think why. ;)
