It would do all the German people with their hearts in the right place a favour. However, Volkswagen is laying off workers in their hometown of Wolfsburg while heavily relying on their nearshored cheap Hungarian workforce in Győr, Hungary. They will take the money they get from that, and lobby the many times reelected centre-right German government to keep Hungary in, so the biggest engine factory of VW keeps being inside Schengen.
Hungary will get kicked out as soon as the EU will enforce that original ICE car sale ban by 2035.
So could raising wages.
