This.You're right. The standard of living is absolute shyte in most of Central and West Africa.
Forget this numbers business. If you want to live a decent life in Africa and you have a bit of money:
1.South Africa
2. Botswana
3. Namibia
4.Ghana
5. Kenya
6. Zambia
If you don't mind living in a non-Black country then Seychelles and Mauritius are your best bet.
My opinion
Most of these westernized brehs are not built for West Africa like that.
They need to move to Johannesburg or Cape Town, there's a gang of expat black Americans and the standard of living, schools, universities and overall amenities are world class.
