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.
