What is the importance of Moore's visit to South Africa as noted in the book, The Other Wes Moore: One Name, Two Fates?

South Africa was a physical representation of the racial divide in America and other countries. Apartheid was illegal, but it was still more or less a way of life. The races were divided geographically, economically, and socially. Moore was able to visit South Africa and understand race more thoroughly. Additionally, he was able to see real poverty up close.
