     Worin liegt denn der Wert dieses Posts? Gehört wohl eher auf 𝕏, statt auf Reddit - und einen Diskurs regt der Post jetzt auch nicht an. "Fachkräftemangel" weil man die Plattform nicht verstanden hat.

     What is the value of this post? It probably belongs on 𝕏 rather than on Reddit - and the post doesn't stimulate any discourse. "Skilled labor shortage" because people didn't understand the platform.
