Why is South Africa richer than other African countries?

1, South Africa is rich in gold and diamonds, and its mining industry is developed. Basically, every visitor to South Africa can choose a diamond with little money to take away [unprocessed, of course].

2. South Africa is different from Central Africa and North Africa. They are all covered with vast deserts and have a bad climate. South Africa is in the middle latitude, with three coasts, and its climate is better than other African countries ~ ~

3. Being located in the traffic artery, since the Cape of Good Hope was discovered, the basic transportation of ocean ships will naturally pass through the Cape of Good Hope in Africa. Now, large-tonnage ships that cannot be carried by the Suez Canal will still choose to bypass South Africa, and the traffic is very developed.

4. South Africa has various climates in the world, is an English-speaking country, and has developed tourism, which also promotes the economic development of South Africa.
