similar and contrasting ideas

Martin Luther King's essay "Letter from Birmingham Jail" and Chimamanda Adichie's TED talk " the danger of a single story" are both indicate the inequality of the human beings in this world. Their opinion are similar: There is no human equal between the white people and black people, so it is necessary to promote and realize equality in the western countries. However their points of the cause of inequality are different because King and Adichie live in the different age. In king's letter, he said, " Any law that degrades human personality is unjust...false sense of inferiority" He believed the privileged group——white people in the American seldom give up their privileges voluntarily, and the society is filled with the racial discrimination. Therefore, in the Birmingham, one of the most unjust place, any nonviolent campaigns like demonstrations should be necessary and inevitable. Martin Lutter King talk tough in his letter and he was fighting for whole black people in America. Compared with king, Adichie talked more  about herself. In her presentation, she use her personal experiences to demonstrate the inequality in the world. She thought most white people, like John Locke who sailed to West Africa in 1561, have a partial cognizance and critical misunderstanding of the African, and this causes  the existing of inequality. In her presentation, she mentioned her roommate was a "kind of patronizing, well-meaning pity' to her when she came to America at the beginning. It's like what she did to Fide's poor family when she very young. The inequality exists because people sometime do not know clearly about you and do not find advantages you have. These are the different ideas from King's essay and Adichie's talk.

Question for discussion:
King and Adichie live in the different age, but they have the similar opinion. That means the inequality still exists in the world. Do you think the inequality between white people and other colored people will always exist or can be eradicated in the future?
