This is a nice, somewhat outdated look at one aspect of how local and international markets collide in Africa. However, I felt that the narrator conflated Zambia's specifics with Africa's generalities. For a viewer who is not informed about Africa, this could lead to misunderstandings and misinterpretations. For example, the film highlights the fact that Indians often control the importation of goods. This is a phenomenon specific to Southern and Eastern Africa.
Furthermore, the film does not address its Anglo-centrism. Zambia is a former British protectorate and therefore has a very different history than francophone or lusophone countries. It would have given a much more balanced point of view to follow a buy'em sell'em in Cameroon or another francophone country. It was also interesting the filmmakers choose to use many obviously Malian songs for the soundtrack. Perhaps the assumption is that American and European viewers will be unable to notice the difference or that since the film is about "Africa," it was not important to choose Zambian music.
If this topic is of interest to you, other issues of local people being unable to access local products (either because they are no longer being created, they are too expensive, or they are simply unavailable) include milk (ie Nido), chocolate, rice, some juices, and more.
Finally, I feel that this films misses a great opportunity to highlight the ingenuity that has allowed Africans to survive and sometimes flourish in the economic conditions of the past 30 years. People selling clothes for fish, and fish for money? Children making their own toys out of wire, seeds, etc? To me this demonstrates how individuals are doing their utmost to succeed and enjoy life in a cash/market economy that is largely inaccessible to them.
We should highlight the success as well as explain who is to be blamed.
