Spaniards are drawn to Germany as well; the Spanish government has publicly encouraged any that can work in Germany to do so. Germany wants them as long as they speak German and have a skill.
My guess is that the recent trafficking of Muslims was done because Germany needs burger flippers; I don’t see southern Europeans leaving friends & family behind to earn what they’d get from the dole in their own countries anyway. BTW, I think that is why we keep our southern border open; in the NYC metro area unskilled Americans won’t work as burger flippers.
There’s a great breakfast cafe that existed in the 1980s in Arlington, VA. When I got ready to move there in 2010...some guy had advised me to go over and try the place because it was fantastic.
So after I got set up and moved in....I found the place (less than five minutes walking from my apartment). It was the old fashioned breakfast diner that people used to eat in all the time. The shocking thing for me....was that their prices were still in the $7 to $8 range for a breakfast plate....while most in the area were $12 to $15.
But I sat there at the counter and noted that virtually all of the employees were El Salvadorian except for the clerk lady and the manager. All minimum wage people and happy to be working. If you went down the street to the higher priced place...all non-El Salvadorian.
What business operations did over the past decades was keep some pricing at the lower end of the spectrum...by using the migrants.
