Unfortunately the foundational thinking behind this runs deep in German culture, stemming from the social upheaval of the early 1800s when a foreign colonizer introduced the (already natively sought) end of the estate system as a way to pit Germans against each other (and gain loyalists). The resulting loss of privileges agitated the heirs towards successful entrepreneurs: Labeling them as Traitors, Jews, and people that didn’t deserve it. As modern Anti-Semitism was born out of this so was the tendency to see success of others with contempt and failure with glee. Though things have improved, you can still notice it.

Apart from that: How is that de-facto locking in of individuals compatible with the EU‘s foundational freedom of movement?
