Have you ever wondered why Switzerland is the world's second largest exporter of processed coffee, despite never growing a single bean? [1]. Germany is 3rd, Netherlands is 4th. Hmmmm.
Have you ever wondered why all those poor countries around the world sell unprocessed coffee to Switzerland for pennies rather than telling Switzerland to take a hike, processing it themselves and making way more money?
Have you ever wondered why many very poor countries around the world sell their raw minerals for a tiny fraction of the globally accepted price?
After three years on the ground in Africa, my eyes were very wide open. The multi-billion dollar loans from the IMF and World Bank have these countries over a barrel, and if they try to change the status quo, they will be sent back to the dark ages instantly. Spending time in Sudan was very educational, though it means I can never get a visa-wavier for the US. Why do you think that is? (Hint: gas in Sudan was 6 cents a liter..., diesel was half that)
Also very educational to try at get a visa for Ecuatorial Guninea (it has a TON of oil, and a TON of multi-national companies ripping it out). A foreigner can go to the island where the capital is no problem, but try getting permission to go to the mainland - you can't. Even with a valid visa you can't get in. (I camped in view of it here [2] )
Why? Because they don't want you to see what is happening there.
