How did George Washington justify the enslavement of people?

He needed enslaved people to build important structures, such as the White House.

He realized the government had little money and was unable to pay people for their services.

He needed enslaved people to fight against the British so that Americans would have a large enough army.

He claimed enslavement was temporary because of the Gradual Abolition Act, which freed all enslaved people after six months of labor.
