Today the challenges are different, and the success that can be envisioned is a much greater level of success. Why don't we have more black people who have achieved success at the level of Donald Trump? Why have we never yet had a black President or Vice-President of the United States? I'll give you a hint: Although racial prejudice still exists, the real reason is not racism.
The other value is in the lesson: if SB Fuller could achieve success, anybody can.
By the way, I'll make a prediction: The first black President of the United States will be a conservative.
