I spent 3 years in West African, both French and English; Sierra Leone, Liberia and the main base Guinea for 3 years.
Terrible poverty, and rampant corruption at every level of society. Corruption from parking your car to negotiating an oil export contract. At the low end, poverty to the extent that human life is cheapened to the point that the West would not understand.
Despite this, no differences between 'us and them'. Some are driven to make a difference, others will fall down and become UN food aid parasites, just like many of the UK benefit monkeys (see many other threads on this).
The time I spent there was incredible. I saw it from a priveledged and high position, being funded by a Western company, but after 3 years had immersed myself enough to finally start to understand some of the real lives of the locals.
Ultimately, Africa is no different to us, other than they have both stronger and weaker nationalist divisions, more tribal based than us, and because of the poverty, aka out culture and technology shunted into theirs, now have different ways of sorting out their problems.
Africa is a wonderful place, yet dangerous in many parts (West Africa at least!) for the casual visitor. Once you've spent any meaningful time there, it is in your blood. I've been back once since I worked there, and another time to just further up the coast.
