The reason why Slavery was so perpetual in the colonial America was because the people needed the slaves to do the works that they had in the colonies.
This is the term that is used to refer to the system of using slaves to work back in the day in Europe and in the Americas. The slaves were owned as the properties of the white man and they has to carry out all of the biddings of the black man. He was required to provide all of the man power that the whites needed for labor.
This was perpetual at the time because it was the means through which they grew their economy. The white man had farm plantations that they needed the blacks to work on for the sake of money.
