Answer: I would say either Botswana or South Africa.
Explanation:
"Botswana gained its independence in 1966 – at that time, it was one of the poorest countries in the world. Yet, it quickly became an example of development success on the African continent; averaging 5% growth per annum over the past decade. The economy is mainly driven by mining, construction and the service sector. One major problem the country has to deal with is poverty, which is due to high unemployment."
"With its highly developed economy and advanced economic infrastructure, South Africa is a major player on the African continent. Being one of the world’s largest producers and exporters of gold and platinum, the country has considerably developed its financial, legal, energy and transport sectors. Lately, progress has been slowing down and South Africa is known to have one of the highest inequality rates in the world."
