Answer: slavery
Explanation: Indentured servitude was in the very infancy of the colonies there were people that would essentially become apprentices in order to make their way in society. With the introduction of chattel slavery there was no longer a need for indentured servitude as they indentured servants would eventually be able to work for their freedom. Slaves were seen as an endless supply of expendable labor which was far cheaper than indentured servants. Hope this helps!
