Read the excerpt from Up from Slavery by Booker T. Washington. I do not believe that any state should make a law that permits an ignorant and poverty-stricken white man to vote, and prevents a black man in the same condition from voting. Such a law is not only unjust, but it will react, as all unjust laws do, in time; for the effect of such a law is to encourage the Negro to secure education and property, and at the same time it encourages the white man to remain in ignorance and poverty. What is the author’s main claim?
