Sales is given low prestige in Germany. People in general do not like to sell. Germans even less so. High prestige in the German business world is enjoyed by the natural sciences, engineering, manufacturing, law, and until recently, banking and finance. The disciplines of sales, including account management, and marketing enjoy less prestige.
King in Germany is knowledge, research and development, invention, production. Germans in general believe that a product should sell itself. Who needs sales/marketing? Verkaufen – German for selling – begins with ver, the prefix to many German verbs which have a negative meaning.
