During the inquest, what do we learn about Mr. Dalton’s ways with the black community?

When Mr. Dalton is placed on the stand, Max exposes the exorbitant rents and segregating practices and policies of the Dalton's South Side Realty Company. Dalton admits that he simply assumed that blacks were happier living in their own neighborhoods and after he prides himself on helping his employees get an education, he admits that he has never offered employment to any educated blacks.
