The Nationalism usually ends when they want cheap labor. Then it's okay for foreigners to come in, unless they advance their status through hard work economically and socially
It absolutely isn't expensive.
Send last year a big 30kg package from Austria to Germany (because I was moving but didn't want to drive all the shit), was charged something between 20-30€, and I believe that's the same price in all of the EU
They do, but the farmers have to participate in an USDA program to prove that they haven't used weird hormones and other "optimizations" in their livestock
Aber die Bahnen müssen bereits ab 60 Minuten bluten wenn etwas schiefgeht, obwohl der Betrieb deutlich komplexer ist als Fliegen..
