Although it shows almost all of the process involving the production of chocolate, this shows completely brushes off the central problem in this situation, the complete an utter oligopoly that reigns supreme in that industry.
I'm not much of a knowledgeable person in terms of trade agreements, but I'm absolutely sure that an oligopoly like this one can only be maintained by stringent government regulations, so I carefully watched the documentary in search of government intervention.
Much to my surprise, the show mentions, only by passing, the limited cocoa exporting licenses that the Ivorian government grants every year, a 100 licenses a year to be exact, on it's own this creates a barrier which prevent more competitors to enter the market with better opportunities for all involved.
The other part in this episode I was surprised that it was not talked about more, is the clear price control the Ivorian government is imposing on the cocoa pod market. I'm no historian, but in every single instance I've found in which price control has been instituted by a government entity the results have been horrible for every one involved, this is because it limits the information that the market is sending to producers through the price, if you control the price it means that you are limiting the information that suppliers need to satisfy the most amount of customers possible.
In other words, while cocoa corporations are absolutely guilty of corrupt and morally dubious behavior in their production enterprises, the government intervention is the one trying to solve market failures by instituting limitations to what the free market can do to maximize the profit everybody involved can get, essentially trying to protect national production by creating prolems in every part of the production phase of chocolate.
