After the Wall came down, many of East Germany’s “guest workers” (to use the West German term) had to go back home. There were around 16,000 such workers from Mozambique. East Germany had sent money to the government of Mozambique - the former workers haven’t seen any of it, and most are living in poverty now. This is the subject of Malte Wandel’s Einheit, Arbeit, Wachsamkeit. Unfortunately, the text and interviews are in German only.
