Answer: Well, that was an tough question. Because Europeans already have some colonies in the Africa. And they think the native africans will overturn them so they capture them and make them slave. When English settlers settled in Virginia, they use slaves so they didn’t need to do any work. And use the production send back to the UK and manufact it to the goods, and send back to the Africa for more slaves, as know as trans-Atlantic Trade. We can also think about this as the Africans were buy from the African settlers. With that slaves been carried from the Africa, they can use these slaves to do their works.
Anyways, American settlers use the African slaves on the plantation so they can gain the production with out paying labors and working.
