Africans believe in the value of an education. African-Americans, less so.
Although the African American community continues to shrink, those emigrating from Africa to Silicon Valley seem to have increased.
The work ethic is still present in many Africans and education is highly valued.
One of my favorite professors was from Africa. After the college hired him, they realized that he was very conservative and (Gasp) a Christian. He once saw a show on cable about coconut plantations, and he was fighting mad the next day. He was angry that the show portrayed the farms as exploiting children. He was literally yelling that his working on those very farms allowed him to get his degree and presented the a huge opportunity in his country.
The school never really figured out what to do with him. LOL
