Answer:
In the 1st Chapter of his book Up from Slavery (page eleven), Booker T. Washington states:
"Then, when we rid ourselves of prejudice, or racial feeling, and look facts in the face, we must acknowledge that, notwithstanding the cruelty and moral wrong of slavery, the ten million Negroes inhabiting this country, who themselves or whose ancestors went through the school of American slavery, are in a stronger and more hopeful condition, materially, intellectually, morally, and religiously, than is true of an equal number of black people in any other portion of the globe."
