The magic of America IS e pluribus unum.
Sure, blessed with a ton of mineral and other raw goods wealth, but as in China, Egypt, Mesopotamia, Persia, Rome, Mali, Spain, London, then New York and Los Angeles and San Francisco, it is the mixing of people that brings ideas togehter and sparks innovation and development and thus progress and wealth.
You really think the EU is blindly admitting a crap ton of young Arab & African men naively believing they're well dressed refugees fleeing war and accidentally their own families? Wake up, son, problem with you hate jizz snorting dumbasses is that you never stop to consider the fact that maybe, just maybe you may be right. Europe is trying to dupilicate the American miracle.
One GLARING problem with your European superiority myth is the simple fact that THEY were never able to accomplish what America has. Sure, the Brits have done some things, but they'd still be coughing up lung along with coal dust imbued muscus getting those big clunky iron dragons spitting cross country while harlots sold their hair for wigs and bodies to working men laboring 16 hrs per day in soot pumping factories like it was still the 1880s just to get some boiled cabbage on the table.
Immigrants provide cheap labor, ideas, business, growing markets, evolution.
If you truly think Merkel's quotas or our cute Santuary Cities are for the sake of some wretchedly ignorant forced altruism, then you are truly every bit as stupid as you pretend to be.
They're using you, you silly gimp, and no, it ain't thuh conniving Jewz hiding out in attics plotting a takeover someday that is not yet today, it IS this right in-front-of-your-eyes not-so-Deep State.
